O’Farrelly is one of five daughters and three sons of Peter Dominic Farrelly and Ann Farrelly (née Sheridan), a family with a traditional interest in the Irish language. After her articles Glimpses of Breffni and Meath are published in The Anglo-Celt in 1895, the editor, E. T. O’Hanlon, encourages her to study literature. Graduating from the Royal University of Ireland (BA 1899, MA 1900), she is appointed a lecturer in Irish at Alexandra College and Loreto College. A founder member in 1902, along with Mary Hayden, of the Irish Association of Women Graduates and Candidate Graduates, to promote equal opportunity in university education, she gives evidence to the Robertson (1902) and Fry (1906) commissions on Irish university education, arguing successfully for full co-education at UCD. Appointed lecturer in modern Irish at UCD in 1909, she is also a member of the first UCD governing body and the National University of Ireland (NUI) senate (1914–49). In 1932, on the retirement of Douglas Hyde, she is appointed professor of modern Irish at UCD, holding the position until her retirement in 1947. She is also president of the Irish Federation of University Women (1937–39) and of the National University Women Graduates’ Association (NUWGA) (1943–47).
One of the most prominent women in the Gaelic League, a member of its coiste gnótha (executive committee) and a director of the Gaelic press An Cló-Chumann Ltd, O’Farrelly is a close friend of most of its leading figures, especially Douglas Hyde, Kuno Meyer, and Eoin MacNeill. One of Hyde’s allies in his battle to avoid politicising the league, she is so close to him that students at UCD enjoy speculating about the nature of their friendship. She advocates pan-Celticism, but does not get involved in disputes on the matter within the league. A founder member, and subsequently principal for many years, of the Ulster College of Irish, Cloghaneely, County Donegal, she is also associated with the Leinster and Connacht colleges and serves as chairperson of the Federation of Irish Language Summer Schools.
Having presided at the inaugural meeting of Cumann na mBan in 1914, espousing its subordinate role in relation to the Irish Volunteers, O’Farrelly leaves the organisation soon afterwards because of her support for recruitment to the British Army during World War I. A close friend of Roger Casement, in 1916, along with Col. Maurice Moore she gathers a petition that seeks a reprieve of his death sentence. She is a member of a committee of women which negotiate unsuccessfully with Irish Republican Army (IRA) leaders to avoid civil war in 1922, and is heavily defeated as an independent candidate for the NUI constituency in the general elections of 1923 and June 1927. In 1937 she is actively involved in the National University Women Graduates’ Association’s campaign against the constitution, seeking deletion of articles perceived as discriminating against women.
Popular among students at UCD, O’Farrelly has a reputation as a social figure and entertains frequently at her homes in Dublin and the Donegal Gaeltacht. A founder member (1914) and president (1914–51) of the UCD camogie club, she persuades William Gibson, 2nd Baron Ashbourne, to donate the Ashbourne Cup for the camogie intervarsities. She is also president of the Camogie Association of Ireland in 1941–42. A supporter of native Irish industry, she is president of the Irish Industrial Development Association and the Homespun Society, and administrator of the John Connor Magee Trust for the development of Gaeltacht industry. A poet and writer in both Irish and English, often using the pseudonym ‘Uan Uladh’, her principal publications in prose are The reign of humbug (1900), Leabhar an Athar Eoghan (1903), Filidheacht Segháin Uí Neachtáin (1911), and her novel Grádh agus crádh (1901); and in poetry Out of the depths (1921) and Áille an domhain (1927).
McMaster is born as Andrew McMaster, the son of Liverpool-born Andrew McMaster (1855–1940), a master stevedore, and Alice Maude née Thompson (1865–1895). A number of sources make the erroneous claims, based on details supplied by McMaster himself, that he is born in 1893 or 1894 or even 1895 in County Monaghan in Ireland but, according to the Birth Register and the 1901 United Kingdom Census, he is actually born in 1891 in Birkenhead, England. Like his future brother-in-law Micheál Mac Liammóir, who is born in London as Alfred Willmore but claims to have been born in Cork to Gaelic-speaking parents, McMaster reinvents himself as Irish and claims for himself the town of Monaghan as his birthplace, and Warrenpoint, County Down, as the scene of his earliest memories.
At the age of nineteen McMaster gives up a career in banking to pursue one on the stage. He moves to Ireland and tours the country with the O’Brien-Ireland theatrical company from 1910 to 1914. Success quickly follows with his appearance as Jack O’Hara in Paddy the Next Best Thing at the Savoy Theatre (1920). From 1921 he tours Australia in this and other plays, and in 1925 forms his own company, the McMaster Intimate Theatre Company, a ‘fit-up‘ company to tour in the works of Shakespeare, mainly in Ireland but also in Britain and Australia, touring with his theatrical company until 1959. One of the last actor-managers “of the old school – and an epitome of the type,” on occasions he persuades a ‘big name’ to act with his company as a draw for audiences. Frank Benson (1928), Sara Allgood (1929) and Mrs. Patrick Campbell appear with him.
In 1933 at the Shakespeare Memorial Theatre in Stratford-upon-Avon McMaster appears as Hamlet opposite Esme Church as Gertrude, Coriolanus, Macduff in Macbeth, Leonato in Much Ado About Nothing, Prince Escalus in Romeo and Juliet, and Petruchio in The Taming of the Shrew. His greatest roles are as Othello and as Shylock in The Merchant of Venice, to which he adds King Lear in 1952. Just before World War II he and his company appear at the Chiswick Empire in a Shakespeare season. He tours the United States as James Tyrone in Eugene O’Neill‘s Long Day’s Journey into Night in 1956. Having ‘a great organ voice,’ Harold Pinter, who acts in his company in Ireland from 1951 to 1953 and calls him ‘perhaps the greatest actor-manager of his time,’ later describes McMaster as ‘evasive, proud, affectionate, shrewd, merry.’ In his brief biography Mac (1968), Pinter recalls, “Mac gave about a half dozen magnificent performances of Othello while I was with him… At his best he was the finest Othello I have see. [He] stood dead in the centre of the role, and the great sweeping symphonic playing would begin, the rare tension and release within him, the arrest, the swoop, the savagery, the majesty and repose.”
McMaster’s only film role is an uncredited appearance as the Judge in Sword of Sherwood Forest (1960).
In 1924 McMaster marries the actress and designer Marjorie Willmore (1894–1970), the sister of Micheál Mac Liammóir. They have two children, the actors John Christopher McMaster (1925–1995) and Mary-Rose McMaster (1926–2018).
McMaster trains a generation of actors who tour with his company and go on to achieve success as actors. These include Pauline Flanagan, Milo O’Shea, T. P. McKenna, Kenneth Haigh, Henry Woolf, Harold Pinter, Donal Donnelly and Patrick Magee. It is while they are touring with McMaster’s company that the actor and dramatist Micheál Mac Liammóir and the actor and producer Hilton Edwards first meet and begin their lifelong partnership.
McMaster’s biography, A Life Remembered: A Memoir of Anew McMaster by his daughter Mary-Rose McMaster, is published in 2017. Harold Pinter also publishes a short biography, Mac, in 1968.
León Ó Broin, senior civil servant, historian, and author, is born Leo Byrne on November 10, 1902 at 21 Aungier Street, Dublin, the second of four sons of James P. Byrne, a potato factor’s bookkeeper, and Mary Byrne (née Killeen), daughter of a seaman who abandoned his family.
After early education in convent school, Ó Broin attends Synge Street CBS, where he is especially adept at languages. After working in several minor clerical employments, he becomes a clerk in the Kingsbridge headquarters of the Great Southern Railway. Joining a local Sinn Féin club, he canvasses for the party in the College Green ward during the 1918 Irish general election. Sent from an early age to Irish language classes by his father, he attends the Irish summer college in Spiddal, County Galway, and joins the Gaelic League, becoming by early 1921 secretary of central branch. He writes articles for the league’s successive weekly organs, each in its turn suppressed by the authorities. Despite regarding such writing as practice work within a language he is yet learning, he is selected best writer of Irish at the 1920 Dublin feis.
Arrested with his father and two brothers just before Christmas 1920 when Black and Tans discover a letter in Irish on his person during a house raid, Ó Broin is imprisoned for several weeks in Wellington Barracks. Leaving his railway job, he works as a clerk in the clandestine office of the Dáil ÉireannDepartment of Agriculture (1921–22). During the Irish Civil War, with departmental work at a standstill, he joins the National Army as a commissioned officer assigned to general headquarters staff at Portobello Barracks. Having recently commenced legal studies at the King’s Inns and University College Dublin (UCD), he handles army legal matters, such as compensation claims for damage to property.
Called to the bar in 1924, Ó Broin enters the civil service. Assigned to the Department of Education (1925–27), he was involved in launching the Irish language publishing imprint An Gúm, intended to redress the paucity of reading material, apart from school texts, in the language. Transferred to the Department of Finance (1927), he serves as estimates officer and parliamentary clerk, and is assistant secretary of the economy committee established by the Cumann na nGaedheal government to make recommendations on reductions in current expenditure. Appointed private secretary to the Minister for Finance (1931–32), he serves both Ernest Blythe and the first Fianna Fáil minister, Seán MacEntee. Promoted to assistant principal (1932), and to principal officer (1939), he represents the department on the Irish Folklore Commission, and serves on the interdepartmental committee that, after the disastrous Kirkintilloch bothy fire in 1937, investigates seasonal migration to Scotland. During the emergency he is regional commissioner for Galway and Mayo (1940–45), one of eight such officers charged with organising contingency preparations for dealing with the likely collapse of central administration in the event of invasion by any of the wartime belligerents.
Transferred out of Finance, Ó Broin becomes assistant secretary (1945–48) and secretary (1948–67) of the Department of Posts and Telegraphs, administering both the postal service and telecommunications. He works closely with Fianna Fáil minister Patrick Little to improve the range and quality of music offered by the broadcasting service, playing a large part in the decision to form and adequately staff a full Radio Éireann symphony orchestra. He represents Ireland in several post-war conferences in Europe and America that reorganise the international regulation of broadcasting activities. He is elected to the European Broadcasting Union‘s administrative council (1953). He establishes and serves on a departmental committee in 1953 that studies all facets of launching a television service.
A devout but liberal Catholic, Ó Broin is prominent for many years in the Legion of Mary, founded by his close friend and civil-service colleague Frank Duff. President of a legion presidium of writers, actors, and artists, he is first editor (1937–47) of the quarterly organ Maria Legionis. Sharing Duff’s ecumenism, he belongs to the Mercier Society, the Pillar of Fire Society, and Common Ground, groups organised by Duff in the early 1940s to facilitate discussion between Catholics and, respectively, protestants, Jews, and secular intellectuals. The first two are suspended amid disapproval by the Catholic Archbishop of Dublin, John Charles McQuaid.
On retirement from the civil service in 1967, Ó Broin concentrates on the parallel career of research and writing that he had cultivated over many years. Having begun writing articles and short stories in Irish from his earliest years in the Gaelic League, he publishes his first collection of short stories, Árus na ngábhad, in 1923. With the establishment of An Gúm, he publishes three more collections of original short stories and translations of such masters of the genre as Alexander Pushkin, Prosper Mérimée, Guy de Maupassant, and Jerome K. Jerome. He translates several popular modern novels, including Robert Louis Stevenson‘s Kidnapped and H. G. Wells‘s The War of the Worlds. Active as secretary, actor, and writer with the state-subsidised Gaelic Drama League (An Comhar Drámaíochta), which produces Irish language plays, he publishes many plays in Irish, both original and translated. His best-selling book in Irish is Miss Crookshank agus coirp eile (1951), about the mummified corpses in the vaults of St. Michan’s Church, Dublin.
Ó Broin writes prolifically on modern Irish history and biography. His Irish language biography of Charles Stewart Parnell (1937), the first full-scale study of its kind in Irish since the commencement of the language revival, is a landmark publication, praised for the quality of its prose by such critics as Frank O’Connor and Seán Ó Faoláin. His biography of Robert Emmet, published in Irish in 1954, and awarded the Douglas Hyde prize, pioneers the scholarly subversion of the romantic myth surrounding its subject, and includes consideration of the political and social context. The subjects of subsequent biographies include Richard Robert Madden, Charles Gavan Duffy, Joseph Brenan, Michael Collins, and Frank Duff.
Ó Broin takes a largely biographical approach to historical writing, researching neglected aspects of pivotal historical events, and basing his studies on previously unexploited primary sources, often the papers of a single individual, whose career serves as the linchpin of his narrative, filtering events through the perspective of that person. Another vein of his scholarship is his primary research into the history of Irish separatism, especially with sources in the Irish State Paper Office.
Ó Broin receives an honorary LL.D from the National University of Ireland (NUI) in 1967. Elected a member of the Royal Irish Academy (RIA) in 1971, he is a council member (1974–76) and senior vice-president (1976–77), and chairs the group whose recommendations results in the academy’s establishment of the National Committee on International Affairs. He is president of the Irish Historical Society (1973–74), and a member of the Irish Manuscripts Commission.
In 1925 Ó Broin marries Cait Ní Raghallaigh, an office assistant reared in Baltinglass, County Wicklow, whom he met in the Gaelic League. They have two sons and three daughters. After residing in the south city suburbs, they move to Booterstown, County Dublin in the 1930s, and from there to the Stillorgan Road in the 1950s.
Ó Broin dies February 26, 1990 in Dublin, and is buried in Deans Grange Cemetery. His papers are in the National Library of Ireland (NLI). His eldest son, Eimear Ó Broin, is an accomplished musicologist and assistant conductor of the several Radio Éireann orchestras (1953–89).

From a Unitarian background, Praeger is raised in Holywood and attends the school of the Reverend McAlister and then the nearby Sullivan Upper School.
Praeger works in the National Library of Ireland in Dublin from 1893 to 1923. He co-founds and edits The Irish Naturalist, and writes papers on the flora and other aspects of the natural history of Ireland. He organises the Lambay Survey in 1905-06 and, from 1909 to 1915, the wider Clare Island Survey. He is an engineer by qualification, a librarian by profession and a naturalist by inclination.
Praeger is instrumental in developing advanced methodologies in Irish botany by inviting Knud Jessen, the acclaimed Danish expert in Glacial and Post-Glacial flora, to undertake research and teaching in Ireland. This leads to the establishment of ‘paleoecology‘ as a distinct field of study in Ireland.
A vice-county system is adopted by Praeger dividing Ireland into forty vice-counties based on the counties. However, the boundaries between them does not always correspond to the administrative boundaries and there are doubts as to the correct interpretation of them.
Praeger dies on May 5, 1953 and is buried in Deans Grange Cemetery, Dublin, together with his wife Hedwig. His younger sister Rosamond Praeger is a sculptor and botanical artist.

Deane is educated at Trinity College, Dublin, from 1845 to 1849. On January 29, 1850, he marries Henrietta Manly, daughter of Joseph H. Manly of Ferney, County Cork. He and his wife have several children.
Deane’s work on the conservation of St. Canice’s Cathedral, Kilkenny, is less successful and brings him into conflict with the dean and chapter, and in particular with the treasurer James Graves. It is possibly his interest in the restoration of medieval buildings which leads to his appointment as the first Inspector of National Monuments under the Irish Board of Works after the disestablishment of the Church of Ireland brought ruined buildings under their care. His work includes St. Cronan’s Church, Roscrea, County Tipperary.
In contemporary circles, Deane’s partner Woodward is seen as the creative influence behind the business, and their practice suffers after his early death on May 15, 1861. Nevertheless, Deane continues to work with his son, Thomas Manly Deane, designing the National Museum of Ireland and National Library of Ireland in Kildare Street, Dublin. He is knighted in 1890.
On November 8, 1899, Deane dies suddenly in his office on St. Stephen’s Green, into which he had only just moved. He is buried in Deans Grange Cemetery, where his son Thomas designs and erects a cross in his memory.
O’Shea is discovered in the 1950s by Harry Dillon, who runs the 37 Theatre Club on the top floor of his shop, the Swiss Gem Company, 51 Lower O’Connell Street, Dublin. Early in his career he tours with the theatrical company of Anew McMaster.
O’Shea begins acting on the stage, then moves into film in the 1960s. He becomes popular in the United Kingdom, as a result of starring in the BBC sitcom Me Mammy alongside Yootha Joyce. In 1967–68 he appears in the drama Staircase, co-starring Eli Wallach and directed by Barry Morse, which stands as Broadway‘s first depiction of homosexual men in a serious light. For his role in that drama, he is nominated for the Tony Award for Best Actor in a Play in 1968.
Other stage appearances include Mass Appeal (1981) in which he originates the role of Father Tim Farley, for which he is nominated for the Tony Award for Best Actor in a Play in 1982, the musical Dear World in which he plays the Sewer Man opposite Angela Lansbury as Countess Aurelia, Corpse! (1986) and a 1994 Broadway revival of Philadelphia, Here I Come!.
O’Shea’s first wife is Maureen Toal, an Irish actress, with whom he has two sons, Colm and Steven. They divorce in 1974. His second wife is Irish actress Kitty Sullivan, whom he meets in Italy, where he is filming Barbarella and she is auditioning for Man of La Mancha. The couple occasionally act together, such as in a 1981 Broadway revival of My Fair Lady. O’Shea and Sullivan have no children together. They both adopt United States citizenship and reside in New York City, where they both live from 1976.
O’Shea dies on April 2, 2013, in New York City following a short illness at the age of 86. He is buried at Deans Grange Cemetery.
O’Nolan writes prodigiously during his years as a student at University College, Dublin (UCD), where he is an active, and controversial, member of the well known Literary and Historical Society. He contributes to the student magazine Comhthrom Féinne (Fair Play) under various guises, in particular the pseudonym Brother Barnabas. Significantly, he composes a story during this same period titled “Scenes in a Novel (probably posthumous) by Brother Barnabas”, which anticipates many of the ideas and themes later to be found in his novel At Swim-Two-Birds.
In 1934 O’Nolan and his student friends found a short-lived magazine called Blather. The writing here, though clearly bearing the marks of youthful bravado, again somewhat anticipates O’Nolan’s later work, in this case his Cruiskeen Lawn column as Myles na gCopaleen. Having studied the German language in Dublin, he may have spent at least parts of 1933 and 1934 in Germany, namely in Cologne and Bonn, although details are uncertain and contested.
A key feature of O’Nolan’s personal situation is his status as an Irish government civil servant, who, as a result of his father’s relatively early death, is obliged to support ten siblings, including an elder brother who is an unsuccessful writer. Given the desperate poverty of Ireland in the 1930s to 1960s, a job as a civil servant is considered prestigious, being both secure and pensionable with a reliable cash income in a largely agrarian economy. The Irish civil service is fairly strictly apolitical, prohibiting Civil Servants above the level of clerical officer from publicly expressing political views. This fact alone contributes to his use of pseudonyms, though he had started to create character-authors even in his pre-civil service writings. He rises to be quite senior, serving as private secretary to Seán T. O’Kelly and Seán McEntee.
Although O’Nolan is a well known character in Dublin during his lifetime, relatively little is known about his personal life. On December 2, 1948 he marries Evelyn McDonnell, a typist in the Department of Local Government. On his marriage he moves from his parental home in Blackrock to nearby Merrion Street, living at several further locations in South Dublin before his death. The couple has no children.
O’Nolan is an alcoholic for much of his life and suffers from ill health in his later years. He suffers from throat cancer and dies from a heart attack in Dublin on the morning of April 1, 1966. He is buried in Deans Grange Cemetery in Dublin.
Walton is the son of a Methodist minister, Rev John Walton (1874–1936), and Anna Sinton (1874–1906). In those days a general clergyman’s family moves once every three years, and this practice carries him and his family, while he is a small child, to Rathkeale, County Limerick, where his mother dies, and to County Monaghan. He attends day schools in counties Down and Tyrone, and at Wesley College in Dublin before becoming a boarder at Methodist College Belfast in 1915, where he excels in science and mathematics. He obtains degrees in mathematics and experimental science from Trinity College Dublin in 1926.
Walton goes to Trinity College, Cambridge in 1927 where he works with Cockcroft in the Cavendish Laboratory under Ernest Rutherford until 1934. In 1928 he attempts two methods of high-energy particle acceleration. Both fail, mainly because the available power sources could not generate the necessary energies, but his methods are later developed and used in the betatron and the linear particle accelerator. In 1929 Cockcroft and Walton devise an accelerator that generates large numbers of particles at lower energies. With this device in 1932 they disintegrate lithium nuclei with protons, the first artificial nuclear reaction not utilizing radioactive substances and so becomes the first person in history to split the atom.
Although he retires from Trinity College Dublin in 1974, he retains his association with the Physics Department at Trinity up to his final illness. His is a familiar face in the tea-room. Shortly before his death he marks his lifelong devotion to Trinity by presenting his Nobel medal and citation to the college. Ernest Walton dies at the age of 91 in Belfast on June 25, 1995. He is buried in Deans Grange Cemetery in Dublin.

MacDonagh is still a young child when his father is executed in 1916 for his part in the Easter Rising. Tragedy strikes again when his mother dies of a heart attack a year afterwards while swimming at Skerries to Lambay Island, County Dublin on July 9, 1917. He and his sister are then cared for by their maternal aunts, in particular Catherine Wilson.
His parents’ families then engage in a series of child custody lawsuits as the MacDonaghs are Roman Catholic and the Giffords are Protestant. In the climate of Ne Temere, the MacDonaghs are successful.
He and his sister Barbara, who later marries actor Liam Redmond, live briefly with their paternal aunt Eleanor Bingham in County Clare before being put into the custody of strangers until their late teens when they are taken in by Jack MacDonagh.
MacDonagh publishes three volumes of poetry: Veterans and Other Poems (1941), The Hungry Grass (1947) and A Warning to Conquerors (1968). He also edits the Oxford Book of Irish Verse (1958) with Lennox Robinson. He also writes poetic dramas and ballad operas. One play, Happy As Larry, is translated into a number of languages. He has three other plays produced: God’s Gentry (1951), Lady Spider (1959) and Step in the Hollow, a piece of situation comedy nonsense.
MacDonagh also writes short stories. He publishes Twenty Poems with Niall Sheridan, stages the first Irish production of “Murder in the Cathedral” with Liam Redmond, later his brother-in-law, and is a popular broadcaster on Radio Éireann.
MacDonagh is married twice, to Maura Smyth and, following her death after she drowns in a bath whilst having an epileptic seizure, to her sister, Nuala Smyth. He has four children, Iseult and Breifne by Maura and Niall and Barbara by Nuala.
Donagh MacDonagh dies in Dublin on January 1, 1968 and is buried at Deans Grange Cemetery.
Kathleen Daly is born into a prominent Fenian family in Limerick on April 11, 1878, the third daughter of Edward and Catherine Daly. Her paternal uncle, John Daly, is at the time imprisoned for his political activities in Chatham and Portland Prisons in England. He is released in 1896 and returns home to Limerick. When Tom Clarke, who had been imprisoned with her uncle, is released in 1898 he travels to Limerick to receive the Freedom of the City and stays with the Daly family.
In 1901 Daly decides to emigrate to the United States to join Tom, who had been there since 1900, having secured work through his Fenian contacts. They marry on July 16, 1901 in New York City. Through his contacts in the Clan na Gael and the Irish Republican Brotherhood (IRB), Tom Clarke continues to be involved in nationalist activity. Kathleen joins the Gaelic League while in the United States and they return to Ireland in November 1907.
In 1914 Clarke becomes a founder member of Cumann na mBan. Her husband forbids her permission to take an active part in the 1916 Easter Rising as she has orders regardless of how the events pan out. As Tom Clarke is the first signatory of the Proclamation of the Irish Republic he is chosen to be executed for his part in the Easter Rising. Her younger brother, Ned Daly, is also executed for taking part in the rising. She visits both of them before they are executed. After the Rising, Michael Collins establishes contact with her while in prison in his attempts to re-build the IRB network. She also sets up the Irish National Aid Fund to aid those who had family members killed or imprisoned as a result of the Easter Rising, closely aided by Sorcha MacMahon.
Clarke becomes a member of Sinn Féin and in 1917 is elected a member of the party’s Executive. During the German Plot she is arrested and imprisoned in Holloway Prison for eleven months. During the Irish War of Independence she serves as a District Judge on the Republican Courts in Dublin. In 1919 she is elected as an Alderman for the Wood Quay and Mountjoy Wards of Dublin Corporation and serves until the Corporation is abolished in 1925.
Clarke is elected unopposed as a Sinn Féin TD to the Second Dáil at the 1921 elections for the Dublin Mid constituency. She is not re-elected at the 1922 general election, however, and supports the Anti-Treaty forces during the Irish Civil War. In 1926 she becomes a founder member of Fianna Fáil and has to resign from Cumann na mBan. She is re-elected to the short-lived 5th Dáil at the June 1927 election as a Fianna Fáil member for the Dublin Mid constituency but loses her seat at the September 1927 election and does not regain it. She is elected as one of six Fianna Fáil Senators to the Free State Seanad for nine years at the 1928 Seanad election under the leadership of Joseph Connolly. She remains a member of the Seanad until it is abolished in 1936.
In 1930 Clarke is elected to the re-constituted Dublin Corporation for Fianna Fáil along with Robert Briscoe, Seán T. O’Kelly, Thomas Kelly and Oscar Traynor. She serves as the first Fianna Fáil Lord Mayor of Dublin as well as the first female Lord Mayor, from 1939 to 1941. She opposes the Constitution of Ireland as she feels that several of its sections would place women in a lower position that they had been afforded in the Proclamation of the Irish Republic. She is criticised by many in the Fianna Fáil organisation as a result and, while she resigns from the Thomas Clarke Cumann, she remains a member of the Fianna Fáil Ard Chomhairle.
While Clarke does not support the Irish Republican Army (IRA) bombing in England during World War II, she appeals for those sentenced to death by the Irish Government to be given clemency. Ultimately this leads to her breaking with the party completely after her term as Lord Mayor finishes in 1941. She declines to stand as a Fianna Fáil candidate at the 1943 general election.
In 1966, as part of the celebrations of the Easter Rising, Clarke and other surviving relatives are awarded honorary doctorates of law by the National University of Ireland. Following her death on September 29, 1972, she receives the rare honour of a state funeral. She is buried at Deans Grange Cemetery, Dublin.
