Percy painted a large view of Grange over Sands in 1874. He must have used sketches done on the spot such as these as reference for his larger dramatic studio canvases. A member of the extensive Williams family of at least three generations of landscape painters descended and trained by the patriarch, Edward Williams, who died in 1855. Like his relatives Henry John Boddington, Arthur Gilbert and Charles Leslie, Percy changed his name in order that he shouldn't be thought a member of the 'Williams factory.'
