In King Stephen's Charter to Shrewsbury Abbey, the earliest mention of William Fitz Alan is made. It notes that William was the son and heir of Alan Fitz Flaald, in the presence of the whole county and with his own seal (King Stephen), confirms all things given by his father to the Shrewsbury Abbey.
In 1136, William Fitz Alan's hereditary Shrievalty of discharging the office, as well as holding the estates of the Sheriff of Shropshire, was recognized by King Stephen. in the spring of 1138, with the concurrence of King Stephen, William was the Casstellan of Shrewsbury, an office which later devolved on the acting Sheriff.
In May 1138, Robert the Consul formally renounced all allegiance to King Stephen, and later ten or twelve of the strongest Castles joined that summer in the Kingdom, including William Fitz Alan. They sided with Empress Maude and her claim to the throne. When Henry Duke of Normandy landed in England to claim the "Crown," January 1153, it is probable that William Fitz Alan joined him in his campaign the following summer, yet it wasn't until Henry II succeeded to the throne that Fitz Allan regained his estates.
William's first wife was Constantia, niece of the Earl of Gloucester. She and any issue they may have had were all deceased without issue at the time Fitz Alan regained his estates. William next married the richest heiress of Shropshire, Isabel de Say, Baroness of Clun, At the time of William's death, his son and heir by Isabel de Say was likely no more than the age of five years.
