Adeliza

Adeliza or Adelida (died before 1113) was a daughter of William the Conqueror and his wife, Matilda of Flanders. There is considerable uncertainty about her life, including her dates of birth and death. She was usually the first daughter in lists of William's children, for example in a mortuary roll prepared at her sister's religious house, and thus probably was the eldest. Her inclusion in the mortuary roll indicates that her death preceded the date of its 1113 compilation.
