William FitzAlan was a Norman nobleman who lived in Oswestry and Clun near Shrewsbury, along the medieval Welsh Marches.
[1] Many people today will often confuse William with his father, as their death dates are similar by 5 years.
Because of this, it is important to know that this William was married to Mary Erington, the daughter of Thomas.
[2] 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.
[4] The estates were eventually reclaimed by his younger brother John Fitzalan.
