Maurice FitzMaurice FitzGerald, Irish magnate, soldier, and Justiciar of Ireland from 1272 to 1273, dies in Ross, County Wexford, on September 2, 1277. His family comes to epitomise the ideal of cultural synthesis in Ireland, becoming “more Irish than the Irish themselves,” fusing Gaelic and Norman customs in Irish identity.
FitzGerald is born in 1238 in Wexford, the second son of Maurice FitzGerald, 2nd Lord of Offaly, and Juliana de Grenville. He has three brothers, Gerald FitzMaurice II, Thomas FitzMaurice and David FitzMaurice. He is known by the nickname of Maurice Mael (from an old word meaning “devotee” in Irish). He is granted his father’s lands in Connacht in exchange for quitclaiming the barony of Offaly sometime before May 20, 1257, when his father, Maurice FitzGerald II, dies at Youghal Monastery.
Before his father’s death, FitzGerald is custos of Offaly, but after the 2nd Lord of Offaly dies, the countess of Lincoln, Margaret de Quincy, sues him for custody of Offaly.
Terrible feuds rage in his time between the Geraldines and the De Burghs. FitzGerald and his nephew John, son of his brother Thomas, capture the justiciar, Richard de la Rochelle, Theobald Butler IV, and John de Cogan I (whose son is married to Maurice FitzGerald III’s sister, Juliana). The capture of the three magnates leads to a private war in Ireland, with the Geraldines on one side and Walter de Burgh and Geoffrey de Geneville on the other. However, the Second Barons’ War in England forces them to come to a temporary peace while they battle Montfortians in the English Midlands in 1266.
In May 1265, FitzGerald is among the chief magnates in Ireland summoned to inform King Henry III of England and his son Prince Edward about conditions in the country, and again in June 1265. These are the result of the private war between the Geraldines and Walter de Burgh, lord of Connacht (who is later made the 1st Earl of Ulster). He is appointed Justiciar of Ireland on June 23, 1272, following the accidental death of his predecessor, James de Audley, on June 11 of that year. His father had served in the same capacity from 1232 to 1245. He holds the post until September 1273, when he is succeeded by Sir Geoffrey de Geneville, Seigneur de Vaucouleurs.
FitzGerald holds four knight’s fees in both Lea and Geashill from Roger Mortimer, 1st Baron Mortimer of Wigmore, who had inherited them from his wife, Maud de Braose.
In 1276, FitzGerald leads a force of men from Connacht against the Irish of County Wicklow. His contingent joins the main army of English settlers jointly commanded by his son-in-law, Thomas de Clare, Lord of Inchiquin and Youghal, who had been made Lord of Thomond earlier that same year, and Sir Geoffrey de Geneville, Maurice’s successor as Justiciar of Ireland. The English under Thomas de Clare and Geoffrey de Geneville attack the Irish at Glenmalure, but are defeated and suffer heavy losses.
Shortly before October 28, 1259, FitzGerald married his first wife, Maud de Prendergast, daughter of Sir Gerald de Prendergast of Beauvoir and Matilda de Burgh, daughter of Richard Mór de Burgh. Together they have two daughters:
- Juliana FitzMaurice (d. 24 September 1300), marries firstly, Thomas de Clare, Lord of Thomond, by whom she has four children; she marries secondly Nicholas Avenel, and thirdly, Adam de Cretynges.
- Amabel FitzMaurice, marries but dies childless.
FitzGerald is Maud’s third husband. She dies on an unknown date. In 1273, he marries his second wife, Emmeline Longespee (1252–1291), daughter of Stephen Longespée and Emmeline de Ridelsford. He and Emeline have no issue.
FitzGerald dies September 2, 1277, at Ross, County Wexford. Emmeline Longespée then fights until her death to claim her dower against her daughter, Juliana, her stepdaughter, Amabilia, and John FitzGerald, who is created 1st Earl of Kildare on May 14, 1316. John is the son of his brother, Thomas by Rohesia de St. Michael. John sues or physically takes lands from the bailiffs of Emmeline, Juliana, and Amabilia.
There is some confusion as to whether Gerald Fitzmaurice FitzGerald is the first or second son of Maurice FitzGerald, 2nd Lord of Offaly. Most, like M. Hickson, of the Royal Society of Antiquaries of Ireland (RSAI) say he is the eldest. Lord Walter FitzGerald says he is the second. In any event, he predeceases his father in 1243. His son, Maurice FitzGerald, drowns in the Irish Channel in July 1268. His son is Gerald FitzMaurice III, born in 1263. Gerald’s marriage is sold to Geoffrey de Geneville, who matches Gerald with his own daughter, Joan, but he dies childless on August 29, 1287.
Maurice FitzMaurice FitzGerald 3rd Earl of Offaly, is succeeded by his nephew John, son of his younger brother Thomas FitzMaurice FitzGerald.
