William FitzWalter (died c. 1160), eldest son, 2nd feudal baron of Eton. His son was William de Windsor (died c. 1176), 3rd feudal baron of Eton, who adopted the surname de Windsor. The feudal barony of Eton soon split into moieties between two members of the family, William de Windsor (died 1215/16) and his cousin, Walter de Windsor (died 1203). Walter de Windsor died without children in 1203, when his two sisters became his co-heiresses. The other moiety continued in the descendants of William de Windsor until at least the time of Richard de Windsor, the son of Richard de Windsor (1258–1326).
Robert FitzWalter, second son, inherited the nearby manor of Eton in Berkshire.
