Robert Beaumont

Isabel Or Elizabeth de Crépi of Vermandois

  • Born: Abt 1075, France
  • Marriage: Robert Beaumont

  General Notes:

Isabel married in 1096 to Robert de Beaumont (born circa 1049 and died
on June 5, 1118), Lord of Beaumont, Post-Audemer Brionne and
Vatteville; Count of Meulan; created 1st Earl of Leicester. Robert de
Beaumont was present at the Battle of Hastings. He was a son of
Roger, Seigneur de Beaumont and Adeline, a daughter of Waleran, Count
of Meulan.
Isabel and Robert had children which tend to be confusing because
Waleran and Robert were twins born in 1104. Both married ladies names
"de Montfort" and both had sons named Sir Robert de Beaumont. One
begins to wonder if perhaps Robert and Waleran were the same person,
but there are differences as shown next.

Waleran de Beaumont (1104 - 1166, twin brother of Robert de Beaumont),
Count of Meulan and Earl of Worcester who married circa 1141 to Agnes
