Maurice FitzGerald, Lord Llanstephan is known to have married Alice de Montgomery, a daughter of
Arnulf de Montgomery. It has been asserted by eminent authorities that Arnulf left, by his wife, Lafracoth, a daughter, Alice, and that she was later the wife of Maurice FitzGerald, son of
Gerald FitzWalter (Gerald of Windsor). By Maurice, one of the first conquerors of Ireland, who died in 1176, she was the mother of Gerald (died 1205), who laid the fortunes of the FitzGeralds of Kildare. (Even Curtis—referenced below—says he cannot find a source for Alice and, on the whole, she seems a) unlikely to have existed and b) impossible for Maurice to have met.) Alice herself was living in 1171, and was then in Ireland with her husband and sons. Maurice FitzGerald, by his wife Alice, had the following children: :*
Thomas FitzMaurice, Lord OConnello (d. 1213) :*
Gerald FitzMaurice, 1st Lord of Offaly (1150–1204) :* William FitzMaurice, 1st Lord of Naas (d. 1199) :* Maurice FitzMaurice, 1st Lord of Kiltrany :* Alexander FitzMaurice :* Robert FitzMaurice :* Nesta FitzMaurice (m.
Hervey de Montmorenci,
Constable of England) '''Lord Llanstephan's''' second eldest son
Gerald FitzMaurice, the 1st Lord of Offaly was the progenitor of the
FitzGerald and
FitzMaurice Earls of Kildare and
Dukes of Leinster. The original
Earldom of Desmond in the
province of
Munster was based on landholdings belonging to the descendants of Maurice's eldest son
Thomas FitzMaurice, Lord OConnello. Thomas's son
John FitzMaurice FitzThomas, who was killed in the
Battle of Callann, became the 1st
Baron Desmond. Others from this line include the
Knights of Glin and
Knights of Kerry. ==Ancestry==
