O’Grady is the son of Admiral Hayes O’Grady and his wife, Susan Finucane. His father is one of the chiefs of the Cinél Donnghaile, the collective name of the O’Gradys. He is a nephew of Standish O’Grady, 1st Viscount Guillamore, and a cousin of the novelist Standish James O’Grady, with whom he is sometimes confused. As a child he is fostered in Coonagh, County Limerick, an Irish-speaking area. There he learns Irish and comes into contact with the Gaelic manuscript tradition, listening to stories read aloud from manuscripts in farmers’ houses during wakes or while carding wool. He maintains this interest in the literary tradition throughout his life.
O’Grady receives his secondary education in Rugby School in Rugby, Warwickshire, England, his name appearing in the school register for August 1846. Subsequently he attends Trinity College Dublin (TCD) from 1850 to 1854 but does not graduate. He is critical of an education system that makes no mention of Irish history and legend. During his student days he becomes a friend of the leading scholars and antiquarians, John O’Donovan, George Petrie and Eugene O’Curry, as well as the bookseller and publisher, John O’Daly. At this time he begins copying Gaelic manuscripts under their direction. He purchases from O’Daly in 1853 a collection in Irish of “tales and other pieces, in prose and verse” which he presents to the British Museum in 1892. He is a founding member of the Ossianic Society in 1853 and becomes its president in 1856. O’Curry attacks him publicly in a review in TheTablet, questioning his ability as a scholar. The publication of the society’s third volume prompts the review.
In 1857 O’Grady moves to the United States where he remains for thirty years. In 1901 he contributes an essay on Anglo-Irish Aristocracy to a collection entitled Ideals in Ireland edited by Augusta, Lady Gregory.
O’Grady is a bachelor all his life and dies on October 16, 1915, in his home in Ballinruan, Hale, Cheshire, England. He is buried in Altrincham cemetery.
O’Grady’s father is the Reverend Thomas O’Grady, the scholarly Church of Ireland minister of Castletown Berehaven, County Cork, and his mother Susanna Doe (or Dowe). The Glebe, his childhood home, lies a mile west of Castletownbere near a famine mass grave and ruined Roman Catholic chapel. He is a cousin of Standish Hayes O’Grady, another noted figure in Celtic literature, and of Standish O’Grady, 1st Viscount Guillamore. After a rather severe education at Tipperary Grammar School, he follows his father to Trinity College, Dublin, where he wins several prize medals and distinguishes himself in several sports.
O’Grady is a paradox for his times, proud of his Gaelic heritage, he is also a member of the Church of Ireland, a champion of aristocratic virtues (particularly decrying bourgeois values and the uprooting cosmopolitanism of modernity) and at one point advocates a revitalised Irish people taking over the British Empire and renaming it the Anglo-Irish Empire.
O’Grady proves too unconventional of mind to settle into a career in the church, and takes a job as a schoolmaster at Midleton College, then in a period of expansion. He also qualifies as a barrister, while earning much of his living by writing for the Irish newspapers. Reading Sylvester O’Halloran’s A general history of Ireland (1778) sparks an interest in early Irish history. After an initial lukewarm response to his writing on the legendary past in History of Ireland: The Heroic Period (1878) and Early Bardic Literature of Ireland (1879), he realises that the public wants romance, and so follows the example of James Macpherson in recasting Irish legends in literary form, producing historical novels including Finn and his Companions (1891), The Coming of Cuculain (1894), The Chain of Gold (1895), Ulrick the Ready (1896) and The Flight of the Eagle (1897), and The Departure of Dermot (1913).
O’Grady also studies Irish history of the Elizabethan period, presenting in his edition of Sir Thomas Stafford‘s Pacata Hibernia (1896) the view that the Irish people had made the Tudors into kings of Ireland to overthrow their unpopular landlords, the Irish chieftains. His The Story of Ireland (1894) is not well received, as it sheds too positive a light on the rule of Oliver Cromwell for the taste of many Irish readers. He is also active in social and political campaigns in connection with such issues as unemployment and taxation.
Until 1898, O’Grady works as a journalist for the Daily Express of Dublin, but in that year, finding Dublin journalism in decline, he moves to Kilkenny to become editor of the Kilkenny Moderator, which is printed at 28 High Street. It is here he becomes involved with Ellen Cuffe, Countess of Desart, and Captain Otway Cuffe. He engages in the revival of the local woolen and woodworking industries. In 1900 he founds the All-Ireland Review and returns to Dublin to manage it until it ceases publication in 1908. He also contributes to James Larkins‘ The Irish Worker paper.
O’Grady’s influence crosses the divide of the Anglo-Irish and Irish-Ireland traditions in literature. His influence is explicitly stated by the Abbey Theatre set with Lady Gregory, W. B. Yeats and George William Russell attributing their interest in the Fenian Cycle of Gaelic tradition in part to him. This leads to him being known as the “Father of the Celtic Revival.” Some of the figures associated with the political party Sinn Féin, including its founder Arthur Griffith, have positive things to say about his efforts in helping to retrieve from the past the Gaelic heroic outlook.
O’Grady marries Margaret Allen Fisher, daughter of William Allen Fisher, and they have three sons. Advised to move away from Ireland for the sake of his health, they leave Ireland in 1918. After living in the north of France and Northamptonshire, they move to the Isle of Wight. He is working on a final exposition of his ideas when he dies suddenly on May 18, 1928.
Founding members include John O’Daly, William Elliot Hudson, John Edward Pigot, Owen Connellan, John Windele, and William Smith O’Brien. The antiquary Standish Hayes O’Grady is a principal member and later becomes its president. By 1860 the list of subscribers numbers 746, six volumes of Transactions are produced, and the preparations for further issues are extant when it ceases operations in 1863.
The group of Irish scholars emerge from competing societies, such as the Celtic Society and the Irish Archaeological Society, focusing on the translation of Irish literature from the “Fenian period of Irish history,” specifically, the mythological works of Oisín and the Fianna, and the promotion of the Irish language. The manifesto stipulates the membership be entirely composed of Irish scholars, the intent being to distinguish itself from similar societies that cater to Anglo-Irish interests and influence. Though such societies have credible scholars as steering members, the work produced is thought to be influenced by the local ascendancy and their royal (English) patrons.
The correspondence of members of the Society reveals a fractious relationship with other important figures of the time, Eugene O’Curry and those of the Royal Irish Academy, and are often frustrated in their attempts to access early manuscripts.
