Other names for Juliana were Julian, Juliane and DE THOMOND.
"Juliana FitzGerald, Lady of Thomond (c. 1263 \endash 24 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.
Early life and family
Juliana FitzGerald was born around 1263 in Dublin, Ireland, the eldest daughter of Maurice FitzMaurice FitzGerald, 3rd Lord of Offaly, Justiciar of Ireland and his first wife, 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, 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 mother Maud died on an unknown date. Her father married secondly in 1273, Emmeline Longespee, but fathered no children by her. It had been previously believed that Emmeline was Juliana's mother, but many genealogists, including Douglas Richardson, have since established that the mother of Juliana and her sister Amabel was Maud de Prendergast. And since Emmeline's heiress was Maud La Zouche, wife of Robert de Holland, 1st Baron Holand, and the granddaughter of her elder sister, Ela Longespee, this is further proof that she died childless. The Complete Peerage also confirms this.
Marriages and issue
In February 1275, at the age of about twelve years, Juliana married her first husband, Thomas de Clare, Lord of Inchiquin and Youghal. He was the second eldest son of Richard de Clare, 5th Earl of Hertford, 2nd Earl of Gloucester and Maud de Lacy. Thomas was a friend of King Edward I of England, with whom he went on a Crusade. He held many important posts including the Office of Governor of Colchester Castle (1266), Governor of the City of London (1273). He was also the commander of the English forces in Munster, Ireland, and on 26 January 1276, he was granted the lordship of Thomond. He was born in 1245, which made him about eighteen years older than Juliana.
Juliana and her husband Thomas resided at Bunratty Castle, which Thomas constructed in stone replacing the earlier wooden structure. Together Thomas and Juliana had four children:
Maud de Clare (c. 1276\endash 1326/27), married firstly on 3 November 1295 Robert de Clifford, 1st Baron de Clifford, by whom she had issue; she married secondly after 1314 Robert de Welle.
Gilbert de Clare, Lord of Thomond (3 February 1281\endash 1308)
Richard de Clare, Steward of Forest of Essex, 1st Lord Clare, Lord of Thomond (after 1281 \endash 10 May 1318 at the Battle of Dysert O'Dea), married a woman by the name of Joan by whom he fathered one son, Thomas.
Margaret de Clare (c. 1 April 1287 \endash 22 October 1333 / 3 January 1334), married firstly in 1303 Gilbert de Umfraville; she married secondly before 30 June 1308 Bartholomew de Badlesmere, 1st Baron Badlesmere, by whom she had four daughters and one son.
Life at Bunratty Castle was marked by unrest and strife as civil war was waged between rival factions of the powerful O'Brien clan. In 1277, Juliana's husband had his former ally Brian Ruad, the deposed King of Thomond, hanged for treason at Bunratty.
Thomas was killed in battle on 29 August 1287, leaving Juliana a widow at the age of twenty-four with four small children; the youngest, Margaret was not quite five months old. On an unknown date she married her second husband, Nicholas Avenel. He presumably died before 11 December 1291/16 February 1292, as this is when she married her third husband, Adam de Cretynges.
Death and legacy
Juliana died on 24 September 1300. Her numerous descendants included English kings Henry V, Edward IV, Richard III, Mary, Queen of Scots, Anne Boleyn, Mary Boleyn, and Diana, Princess of Wales.
