William was a younger son of Pierre de Grandison and Agnes Neufchâtel. He was the younger brother of a key ally and envoy, for King Edward I of England, Otto de Grandson, Grandison being an anglicisation of Grandson.

He served in the household of Edmund, Earl of Lancaster. He was active in the wars in Gascony and Scotland.[1] During 1292, he was granted a license to crenellate his manor of Ashperton, Herefordshire.
