Name Suffix: Baron Of Oswestry, Sir Knight Ancestral File Number: H11N-GT William FitzAlan, of Clun and Oswestry; dsp 1216. [Burke's Peerage]
Note: Burke's has William dead without issue. Burke's also has John (whom I have a son of this William) being a son of William (father of this William) who died about 1160. I think that would make John almost 100 years old when he died, therefore I am going with the usually less reliable Plantagenet Ancestry andsaying John was son of this William who died 1210, whom I guess Bernard Burke (see citation below) states died about 1172 and had another son William who mayhave dsp 1216.
William Fitz-Alan, in the 12th Henry II [1166], upon the assessment in aid of marrying the king's daughter, certified his knights' fees to be in number thirty-five and a half. He d. about 1172, and was s. by his son, William Fitz-Alan. [Bernard Burke, Dormant and Extinct Peerages, Burke's Peerage, Ltd, London, 1883, p. 200, Fitz-Alan, Earls of Arundel]
