On the west, rear wall of Carsphairn Parish Church, Dumfries and Galloway (formerly in Kirkcudbrightshire), Scotland. He was born at Kirkby Malzeard, Yorkshire, and his two older brothers also served in South Africa - Augustus Ernest, who was later killed in action in France, on the 14th September 1914, as a captain in the King's Royal Rifle Corps, and Adrian, Royal Scots Fusiliers(?).

Neither side of William Harold Cathcart's family seems to have had a direct connection with Carsphairn in Victorian times, so it may simply be that his father had visited the area for game shooting, taking his family with him. The Cathcart clan originated south of Glasgow, in Renfrewshire, so there may also be a family connection with the Carsphairn area that I couldn't find on the internet (and I'm not going to try to dig deep into genealogy records).
