This Patrick son of William is likely to be the Patrick son of William son of Orm who got a royal charter from Alexander III of lands in ABD in 1233. William son of Orm witnessed a number of charters in Perthshire and Angus in the early 13th century, and Patrick son of William was sheriff of Perth in 1237. These point to the likelihood that William was a younger son of Orm of Abernethy.
