In the 11th century, the name FitzOther meant simply son of a man named Other. Historian John Langton Sanford and Alfred Webb stated that Walter was the son of "Lord Otho, an honorary Baron of England, said to have been descended from the Gherardini of Florence";[4][5][6][7] The Fitzgeralds and Gherardinis are recorded communicating in letters dating back to 1413 between the Tuscany branch and the Earls of Kildare regarding their kinship.[8] In 1507, Gerald FitzGerald, 8th Earl of Kildare, the Viceroy of Ireland, was signing his letters as Gerald, Chief in Ireland of the family of the Gherardini.[9]
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).[14]
Robert FitzWalter, second son, inherited the nearby manor of Eton in Berkshire.[15]
