Isabel de Clare, suo jure Countess of Pembroke and Striguil (1172-1220), was a Cambro-Norman-Irish noblewoman and one of the greatest heiresses in Wales and Ireland.

Isabel was described as pleasant, gentle, and extremely attractive. After her brother Gilbert's death in 1185, she became one of the wealthiest heiresses in the kingdom, owning besides the suo jure titles of Pembroke and Striguil much land in Wales and Ireland. She inherited the numerous castles on the inlet of Milford Haven, guarding the South Channel, including Pembroke Castle. She was a ward of King Henry II.

Burial information of Isabel FitzGilbert de Clare at Tintern Abbey:

On July 7, 2006 Alton Rogers received an email from Richard Turner with the Wales government (Richard.Turner@Wales.GSI.Gov.UK) regarding the burial of Isabel, wife of William Marshal at Tintern Abbey. He provided the following from M.P. Siddons (ed) 1996, Visitations by the Heralds in Wales, Alan Sutton Publishing, Stroud, pp 37-39: Isabel de Clare is known to have been buried in the Abbey Church with two of her sons, Walter and Anselm. The chapter house at Tintern is early 13th century in date and the present Abbey Church was started in 1269. So none of these burial slabs will have been in their original position in 1531 when William Fellows visited the tomb of Aoife/Eva of Leinster, Isabel's mother: (Ive Burgh) "in the northe part of sayde Church Lyeth Ive Burgh, doughter to Makmure, King of Lymster in Irelande, and wife to Richard Strangebowe aforewrytten on the other side."


  1. Legend has that William Marshal was cursed by the Irish Bishop of Ferns.
  2. The title of marshal passed to Hugh de Bigod

Clare-671 and Clare-22 appear to represent the same person because: See Research Notes added to Clare-671 (that profile was detached from a different Richard de Clare). Please merge this profile with Clare-22. Thanks!

If nobody objects, I'm going to remove the stylized Renaissance coat of arms from Isabel's profile; it's anachronistic and seems inappropriate for a woman's profile.

Can't find anything to say this Isabel existed. She could be a mutation of Isabel de Clare-644, daughter of the other Richard

Is it acceptable to add a coat of arms to a woman's profile? On the one hand, women didn't bear arms. On the other hand, it's a handy and colorful symbol of family identification. But on the third hand, sometimes (especially in the early centuries) a woman's brothers and father used different coats of arms, and it might take a lot of research to get it right.
