a. Probably the eldest son of his father's (presumed) second marriage, he was the first baron of Offaly. He was with his father at the siege of Dublin in 1171, and after his father's death, his elder brother William gave him half the cantred of Ophelan. By his marriage to Eve, presumably the daughter of Robert de Bermingham, he received the barony of Offaly. His widow married secondly, Geoffrey Fitz Robert, and after his death in 1211, she married, thirdly, Geoffrey de Marsh (or Marisco), sometime Justiciar of Ireland.
b. He was knighted in Jul 1217, and as Maurice FitzGerald, Lord of Lea, the younger, he was one of the formal witnesses to a covenant of dower made in the great church of Naas in Mary 1227. He was summoned in Oct 1229 to London to accompany the King's expedition to Poitou and Gascony , and was appointed Justiciar of Ireland in Sep 1232. He was several times summoned to England as Justiciar, to give counsel on the affairs of Ireland , but in Nov 1245, he was superseded in that office by the appointment of John FitzGeoffrey, a move which the King appears afterwards to have regretted. He is said to have married Juliane, but nothing more is known of her. He died at the monastery of Youghal, which he had founded.
c. In May 1262, he was among the chief magnates in Ireland summoned to inform the King and Prince Edward about the state of that country, and was summoned again in Jun 1265. It had been believed that his (only) wife was Emmeline Longespee, but a recent discovery by Mr. Douglas Richardson (to appear in one of his upcoming publications), indicates Maurice Fitz Maurice (Fitz Gerald) was first married to Maud de Prendergast, and she was the mother of Juliane Fitz Maurice. Go to SGM site for details concerning this discovery.
d. Youngest son of Maurice Fitz Gerald, the Justiciar, he had, from his brother, Maurice, a grant of lands in Sligo . He died at his brother's castle of Lough Mask in 1271.
e. He first appears in records ca 1288, when as John, son of Thomas, he was guardian of part of the Marches of the English Pale, and in 1291 he had protection while in England with the Archbishop of Dublin. He was also engaged in suits concerning his kinsmen's lands, which he appears to have bought from the coheirs. In 1293, he built Sligo Castle , and in the same year and later, was keeper of the castles of Roscommon and Randown. In 1294, he took the Earl of Ulster (Richard de Burgh) prisoner and was also involved in a dispute with another noble, William de Vesci. In 1295, he was summoned to Parliament by John Wogan the Justiciar, who also arranged a truce for two years between the Earl of Ulster and John and the other Geraldines, which became a peace in 1298. John then gave the Earl 3,000 marks and the Earl gave his daughter in marriage to John's son. From 1295 to 1302, he was summoned by the King for military service in Scotland and Flanders . In 1307, he and Edmund Boteler dispersed the robbers of Offaly who had burned Lea Castle . In 1309 he was called upon to cooperate with the Earl of Ulster and other magnates in assembling an Irish force by the following midsummer to serve in Scotland , and in 1311 he was summoned to assist the King's commissioners in quieting discontents in Ireland . When Edward Bruce, brother of King Robert, came to Ireland and was crowned King of Ireland, John Fitz Thomas and others, whose combined forces would have been sufficient to overcome Bruce, intead fell out among themselves and did nothing, but in Feb 1315/16, he joined with the other magnates of Ireland in an obligation to maintain the King's authority against his enemies, the Scots. On 14 May of that year, for his services to the late and present King, he had grants of the castle and town of Kildare , and being then in England , was created Earl of Kildare.
