(Earls of Kildare, p. 15) Fitzgerald's wife was Juliana, daughter of John de Cogan. His eldest son seems to have been Gerald, who predeceased him probably in 1243, and had a son Maurice, who is noticed below. The justiciar's eldest surviving son was Maurice Fitzmaurice [q. v.] (Sweetman, vol. ii. No. 563). Another was probably Thomas MacMaurice (d. 1271, cf. Loch Cé, p. 469), father of John Fitzthomas, the first earl of Kildare [q. v.] Robert Fitzmaurice, who figures so frequently in the Irish documents of the latter half of the thirteenth century, may possibly have been another son.
Maurice Fitzgerald (d. 1268), son of Gerald, the eldest son, inherited the barony of Offaly (Sweetman, vol. ii.) He married Agnes, daughter of William de Valence, uncle of Edward I, and appears to have been drowned in crossing between England and Ireland, 28 July 1268 (Clyn, p. 9; Annals of Ireland, ii. 290, 316; Loch Cé, p. 459; Ann. Four Masters, ii. 404). He must be distinguished from his uncle Maurice Fitzmaurice Fitzgerald (d. 1277) [q. v.] He left an infant heir, Gerald Fitzmaurice, aged three and a half years (Sweetman, Nos. 1106, 2163, p. 467, &c.; Book of Howth, p. 324; Dugdale, i. 776). This child was the ward of Thomas de Clare, brother to the Earl of Gloucester, and, by purchase, of William de Valence. In 1285 he, as baron of Offaly in succession to his father, was attacked by the native Irish of the barony. We find this Gerald Fitzmaurice coming of age about 1286 (Sweetman, vol. ii. Nos. 866-7, 957, 970, 1039, &c.; vol. iii. Nos. 29, 238, 456, p. 75, &c.; Abbrev. Plac. pp. 263, 283), and it is probably he to whom Clyn refers (p. 10) in his crucial passage on the Geraldine succession where he says that 'Gerald, filius Mauricii, capitaneus Geraldinorum' died in 1287 and left his inheritance to his grand-uncle's son John Fitzthomas [q. v.] Some genealogists contend that Gerald Fitzmaurice was son of Maurice Fitzmaurice Fitzgerald (d. 1277) [q. v.], the justiciar. But he was clearly that justiciar's grand-nephew.
[The principal authorities for the life of Maurice Fitzgerald are the English State Documents and the contemporary English chroniclers. The Irish documents may be found in Sweetman's Calendar of Irish Documents, vols. i. and ii. (Rolls Series); Rymer's Fœdera, ed. 1720, vol. i. The chief contemporary English chroniclers are Roger of Wendover, ed. Coxe (Engl. Hist. Soc.); Matthew Paris, ed. Luard, vols. iii. iv. v. (Rolls Series); Thomas Wykes, the Oseney Annals, the Dunstable Annals, ap. Riley's Annales Monastici (Rolls Series), vols. iii. iv. Other important contemporary documents are to be found in the Royal Letters, ed. Shirley, vol. i. (Rolls Series); Documents of the Anglo-Normans in Ireland, ed.. Gilbert, vol. i. (Rolls Series). The chief Irish Annals are the Annals of Loch Cé (Rolls Series), vol. i. ed. Hennessy; Annals of Boyle ap. O'Conor's Scriptores Rerum Hibernicarum, vol. ii.; and the collection known as the Annals of the Four Masters, ed. O'Donovan, vol. ii. Then come the Latin-writing Irish chroniclers: Clyn (fl. 1348) (Irish Archæol. Soc.), ed. R. Butler; a fourteenth-century Annales Hiberniæ, with its fifteenth-century continuation and expansion, both cited above as Annals of Ireland, ap. Chartulary of St. Mary's, Dublin, ed. Gilbert, vol. ii. (Rolls Series); the Annals of Jas. Grace (fl. 1537) (Irish Arch. Soc.), ed. Butler. Hanmer's Chronicle of Ireland (c. 1571) and Campion's History of Ireland (1633) may be found reprinted in the Ancient Irish Histories (Dublin, 1809), but are very untrustworthy, as also are Ware's Annals (English edition, 1705); and Cox's Hibernia Anglicana (ed. 1689). The Earls of Kildare, by the Marquis of Kildare (Dublin, 1857), represents the current genealogy of the Fitzgeralds, and is a careful compilation of facts. See, too, Lodge's Peerage of Ireland, ed. Archdall, 1789, vol. i.; Gilbert's Viceroys of Ireland (Dublin, 1865); and Archdall's Monasticon Hibernicum (editions 1786 and 1873). See also the Book of Howth, ed. Brewer and Bullen, and Hist. and Municipal Documents of Ireland, ed. Gilbert (Rolls Series).]
FITZGERALD, MAURICE Fitzmaurice (1238?–1277?), justiciar of Ireland, was the son and heir of Maurice Fitzgerald (d. 1257) [q. v.], the justiciar (Sweetman, vol. ii. No. 563). His mother is said to have been Juliana de Cogan (Earls of Kildare, p. 15). Being still a minor at his father's death he was claimed as the ward of Margaret de Quinci, countess of Lincoln, the widow of Walter Marshall, of whom the elder Maurice had held the barony of Offaly (Sweetman, vol. ii. No. 563; Doyle, ii. 376, iii. 7; Dugdale, i. 102, 607). He had perhaps come of age two years later (7 Nov. 1259), when he was granted Athlone Castle and the shrievalty of Connaught (Sweetman, vol. ii. No. 631). Next year he was defeated in an expedition against Conor O'Brian at Coill-Berrain in Munster, but succeeded in plundering the O'Donnells, who retaliated on Cairpre (Carbery, co. Sligo) in North Ireland (Loch Cé, pp. 435-7; Ann. Four Masters, sub an.) He led another expedition against Brian Ruadh O'Brien in 1272 or 1273. For the expenses of this campaign he received a hundred marks; and it was perhaps on this occasion that he borrowed from the Dublin citizens the 86l. 19s. which they asked the king to repay in June 1275. This expedition of 1273 was a success, and, according to the Irish annals, Maurice 'took hostages and obtained sway over the O'Briens' (Sweetman,
