Overview
Elizabeth de Clare, 11th Lady of Clare (16 September 1295 – 4 November 1360) was the heiress to the lordships of Clare, Suffolk, in England and Usk in Wales. She was the youngest of the three daughters of Gilbert de Clare, 6th Earl of Hertford and Joan of Acre, and sister of Gilbert de Clare, who later succeeded as the 7th Earl. She is often referred to as Elizabeth de Burgh, due to her first marriage to John de Burgh. Her two successive husbands were Theobald II de Verdun (of the Butler-de Verdun family) and Roger d'Amory.
Marriages
Elizabeth de Clare married three times and had three children; one by each husband. Her father had been one of England's wealthiest and most powerful nobles, and her mother was a daughter of King Edward I of England. When Elizabeth's only brother Gilbert, 7th Earl of Hertford was killed at the Battle of Bannockburn in 1314 aged only 23 and leaving no surviving issue, his property, estimated to be worth £6,000/year, was equally divided between his three full sisters, Elizabeth, Eleanor and Margaret. This made Elizabeth one of the greatest heiresses in England. Her maternal uncle, King Edward II, recalled her to England so he could select a husband for her. She left Ireland for good in 1316, leaving behind her young son, William.
First marriage
She accompanied her brother Gilbert to Ireland for their double wedding to two siblings: the son and daughter of the Earl of Ulster. Elizabeth married John de Burgh on 30 September 1308. He was the heir to the Earl of Ulster, and Elizabeth could expect to be a countess in due course. She gave birth to their only child, a son, in 1312; he would become William Donn de Burgh, 3rd Earl of Ulster. Only a year later, her husband John was unexpectedly killed in a minor skirmish. A widow, Elizabeth remained in Ireland until the death of her brother, Gilbert, at the Battle of Bannockburn compelled her immediate return to England in July 1314.
