From Wikipedia - Juliana FitzGerald :

In February 1275, at the age of about twelve years, Juliana married her first husband, Thomas de Clare, Lord of Inchiquin and Yougal. He was the second eldest son of Richard de Clare, 6th 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 in 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:[3]
Maud de Clare (1276- 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.
Richard de Clare, Steward of Forest of Essex , 1st Lord Clare (1278- 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.
Gilbert de Clare, Lord of Thomond (3 February 1281- 1307)
Margaret de Clare (c.1 April 1287- 22 October 1333/3 January 1334), married firstly in 1303 Gilbert de Umfraville; she married secondly before 30 June 1308 Bartholomew de Badlesmere, 1st Lord 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.[4]
Thomas died on 29 August 1287.
