Donald McCalman married Peggy Cameron. Their son was George Frederick McCalman born 1819 Aharacle, Argyll, Scotland. Alexander McCalman Married Mary Campbell 29 Feb 1812. Archibald McCalman and Ann McDougal married 1800, and Archibald McCalman and Catherine Livingston married 1826. Unable to link Donald McCalman to Alexander, and the two Archibald McCalmans. We are told that Alexander and Archibald (1800) were brothers and that they were first cousins to Donald McCalman. Would appreciate any information on these families.
