General Notes: From Wikipedia:
Walter Fitz Other (fl. 1086; died after 1099) was a feudal baron of Eton in Buckinghamshire (now in Berkshire) and was the first Constable of Windsor Castle in Berkshire (directly across the River Thames from Eton), a principal royal residence o f King William the Conqueror, and was a tenant-in-chief of that king of 21 manors in the counties of Berkshire, Buckinghamshire, Surrey, Hampshire and Middlesex, as well as holding a further 17 manors as a mesne tenant in the same counties.

Origins:
In the 11th century, the name Fitz Other meant simply son of a man named Other. Alfred Webb suggested that Walter was the son of "Lord Otho, an honorary Baron of England, said to have been descended from the Gherardini of Florence"; However, J. Ho race Round considers this to be a fabrication of the fifteenth century.

Marriage and children:
He married Beatrice and had issue:
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 me mbers 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 W illiam 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.
Gerald de Windsor (c. 1075 - 1135), (alias Gerald FitzWalter), third son, the first castellan of Pembroke Castle in Pembrokeshire (formerly part of the Kingdom of Deheubarth), in Wales, who was in charge of the Norman forces in southwest Wales.
