I cannot verify your information. But I too have ancestors from Tilliecoultry, Clackmannan, Scotland. William and Mary Campbell Stalker married about 1830. One son I know of named William Stalker, b. 20 Nov 1832, m. Charlotte Erskine Blair in Clackmann, Clackmannan, Scotland. They had 4 children: Charlotte Blair Stalker, George B. Stalker, William Stalker, and Henry Stalker. Charlotte and George emigated to USA in 1883. Do these names mean anything to you? Glad to exchange information. Thanks.
