William St Clair of Roslin, 20th Baron of Roslin (1700-1778) was a member of the Clan Sinclair.[1] His title, Baron of Roslin, was not a peerage but a Scottish feudal barony. He had an interest in sport and was a skilled golfer and archer. He redesigned the Old Course at St. Andrews to 18 holes thus affecting all golf courses since. He was the son of Alexander St Clair, 19th Baron of Roslin.[2]
