My father's name was William Bain Cormack. He was born in the Caledonian Hotel, Wick, Caithness, Scotland on February 21, 1902. His mother: Margaret Bain. His father: James Cormack (died 1906). Margaret got remarried to a man named Mowatt. The name Bain caught my eye. (There seem to be a lot of Cormacks in Wick.) Could Margaret be Alexander and Catherine's daughter?
