William Fitz Alan was a Norman nobleman who lived in Oswestry and Clun near Shrewsbury, along the medieval Welsh Marches.
[1] William married a daughter of Hugh de Lacy, of which no first name is mentioned in any record known.
When William came to inherit his lands in 1210, King John demanded a fee of 10,000 marks; unable to pay, William was unable to inherit.
[2] He only outlived his father by a few years, dying around Easter 1215.
[3] The estates were eventually reclaimed by his younger brother John Fitzalan.
