Thanks, Frank, very helpful. Out of curiosity, I looked up A. Yewdall, of Wetherby, who was Arthur Yewdall, served in the "9th (Yorkshire [Doncaster]) Company, raised 1900; sponsored by Yorkshire Hussars." Arthur was born in Leeds on 17th February 1871, and died at Garthmyl, Montgomeryshire, on 7th March 1948. At one time he'd been in Canada, working in the fur trade.
Garthmyl isn't a village, it seems to be just Garthmyl Hall, and Arthur Yewdall isn't mentioned as having been one of the owners, so perhaps he was employed there.
A relative of his must have been Albert Yewdall, who the British Museum has listed as a watchmaker between at least 1900-1918, and based in Leeds.
