Juliana FitzGerald

Juliana FitzMaurice, Lady of Thomond (12 April 1266 - 29 September 1300) was a Norman-Irish noblewoman, the daughter of Maurice FitzGerald, 3rd Lord of Offaly, and the wife of Thomas de Clare, Lord of Thomond, a powerful Anglo-Norman baron in Ireland, who was a younger brother of Gilbert de Clare, 6th Earl of Hertford. Juliana was married three times; Thomas being her first. She is sometimes referred to as Juliane FitzMaurice.

Juliana FitzMaurice was born on 12 April 1266 in Dublin, Ireland, the eldest daughter of Maurice FitzGerald II, 3rd Lord of Offaly, Justiciar of Ireland and Maud de Prendergast. She had a sister Amabel who married but was childless. Her first cousin was John FitzGerald, 1st Earl of Kildare. Her paternal grandparents were Maurice FitzGerald I, 2nd Lord of Offaly and Juliana, and her maternal grandparents were Sir Gerald de Prendergast of Beauvoir and the unnamed daughter of Richard Mor de Burgh, Lord of Connacht and Egidia de Lacy. Juliana's maternal ancestors included Brian Boru, Dermot McMurrough, and Maud de Braose.

Juliana's father, Maurice FitzGerald, was married twice, first to Maud de Prendergast and secondly to Emmeline Longespee. It has been some source of contention as to which of his two wives had issue Juliana. However, at her death, Emmeline Longespee did not mention Juliana as her daughter and heir; rather, Emmeline's heir was her niece, Maud la Zouche, wife of Robert la Zouche, 1st Lord Holland. It has been concluded by several reputable researchers that Juliana's mother was Maurice FitzGerald's first wife, Maud de Prendergast. Supporters for Emmeline Longespee being the mother have yet to produce any counter-evidence beyond hearsay.
