Ampherlaw House is a manor house in Lanarkshire, Scotland, near the village of Carnwath and one of the former possessions of the Somerville family. It was built some time in the early 16th century and the members of the Somerville family who held the Ampherlaw estate were cadets of the Lords Somerville of Carnwath and Linton. William Somerville and his family settled at Huntly Hill in Lilydale, where he was a successful farmer, J.P. and lay preacher of the Presbyterian Church.
