She is born Helen Mary Sybil Staunton on December 21, 1892, in Herbert Street, Dublin, to Dorothy Eleanor Redington and Peter Maurice Staunton. Her father is a barrister who later becomes a solicitor. Though he moves to Aram Lodge, Castlerea, County Roscommon where he practises law, she grows up in Dublin and Howth, going to secondary school in Loreto Abbey, Rathfarnham, and later at Loreto Convent, St. Stephen’s Green. She goes on to study German and singing in Koblenz. She marries Albert le Brocquy on December 30, 1915, and settles in Dublin. They have three children, Louis, Noel and Melanie.
Le Brocquy becomes involved in various women’s movements, helping to organise the Women’s International League for Peace and Freedom in July 1926. She is involved with the League of Nations Association as well as helps to establish Irish Civil Rights, PEN International, and Amnesty International in Ireland. She is an active member of Old Dublin Society and for a time president of the Irish Women Writers’ Society. She acts with the Drama League appearing as Helen Staunton. She writes plays and dramatic pieces which are staged by the Drama League at the Abbey Theatre and broadcast by Radio Éireann.
Her writings and work are often historically investigative, finding W. B. Yeats’s birthplace and arguing that Jonathan Swift had a child by Vanessa. She is involved in the Swift Tercentenary celebrations with Cearbhall Ó Dálaigh. As a result of her work, including with Trinity College Dublin Library and representing the Library on the Royal Irish Academy’s National Committee for Anglo-Irish Literature, she is co-opted to the Cultural Committee of the Department of External Affairs and appointed a Trustee of the National Library of Ireland. She is an excellent organiser and fundraiser and is heavily responsible for securing money for the Gate Theatre, Dublin, in 1970. She also initiates the literary prize, the Book of the Year award.
Le Brocquy becomes ill with an undiagnosed illness and dies on September 4, 1973, at the Meath Hospital, Dublin.
Gifford is the second youngest of 12 children born to Frederick Gifford, a solicitor and a Roman Catholic, and Isabella Julia Burton Gifford, a Protestant. The boys are baptised as Catholics and the girls as Protestant, but effectively the children are all raised as Protestants with the girls attending Alexandra College in Earlsfort Terrace.
Gifford returns to Dublin in 1908 and, with great difficulty, tries to earn a living as a caricaturist, publishing her cartoons in The Shanachie, Irish Life, Meadowstreet and The Irish Review, which is edited from 1913 by Joseph Plunkett. She considers emigrating but gives up the idea. Nora Dryhurst, a journalist from London, brings her to the opening of the new bilingual school Scoil Éanna in Ranelagh, Dublin. It is here that she meets Plunkett for the first time. He is a friend of her brother-in-law, another of the future leaders of the 1916 Easter Rising, Thomas MacDonagh, who is married to her sister Muriel.
Gifford’s growing interest in the Roman Catholic religion leads to the deepening of Gifford and Plunkett’s relationship as she begins to discuss Catholic mystical ideas with him. Plunkett proposes to her in 1915, and she accepts and takes formal instruction in Catholic doctrine. She is received into the Catholic Church in April 1916. The couple plans to marry on Easter Sunday that year, in a double wedding with his sister and her fiancé.
After the Rising, Gifford’s brother-in-law Thomas MacDonagh is shot with Patrick Pearse and Thomas Clarke by firing squad on May 3. That day, she hears that Plunkett is to be shot at dawn. She purchases a ring in a jeweler’s shop in Dublin and, with the help of a priest, persuades the military authorities to allow them to marry. She and Joseph are married on the night of May 3 in the chapel of Kilmainham Gaol, a few hours before he is executed.
Grace Plunkett decides to devote herself through her art to the promotion of Sinn Féin policies and resumes her commercial work to earn a living. She is elected to the Sinn Féin executive in 1917.
During the Irish Civil War, Plunkett is arrested with many others in February 1923 and interned at Kilmainham Gaol for three months. She paints pictures on the walls of her cell, including one of the Blessed Virgin and the Christ Child. She is released in May 1923.
When the Civil War ends, Plunkett has no home of her own and little money. Like many Anti-Treaty Republicans, she is the target of social ostracism and has difficulty finding work. Her talent as an artist is her only real asset and her cartoons are published in various newspapers and magazines. She moves from one apartment to another and eats in the city-centre restaurants but has no wish to remarry. Her material circumstances improve in 1932 when she receives a Civil List pension from Éamon de Valera‘s Fianna Fáil government. She lives for many years in a flat in Nassau Street with a balcony overlooking the sports ground of Trinity College.
Plunkett’s in-laws refuse to honour her husband’s will, in which he leaves everything to his widow. Legally, the will is invalid because there is only one witness, rather than the required two, and the marriage takes place after the will is made, automatically revoking it. For years she receives nothing, so she begins legal proceedings against her in-laws in 1934. The Count and Countess Plunkett settle out of court, and she is paid £700, plus costs.
At around this time Plunkett joins the Old Dublin Society, where she meets the noted Irish harpsichord maker Cathal Gannon. When Cathal marries, she gives him and his wife Margaret a present of two single beds and a picture. From the late 1940s onwards, her health declines. In 1950 she is brought to St. Vincent’s Hospital. She convalesces in a nursing home, which she does not like, mainly because it restricts her freedom.
Grace Gifford Plunkett dies suddenly on December 13, 1955, in her apartment in South Richmond Street, Portobello. Her body is removed to St. Kevin’s Church, Harrington Street and among the attendees at her funeral is PresidentSeán T. O’Kelly. She is buried with full military honours close to the republican plot in Glasnevin Cemetery.
