Vicki Cooper is the expert on this family. It starts with Joseph Albert Gillmore (1787 No. Ire.-1863 Co. Antrim, Ire) he married Ann Agnes English and had a large family with her; but he also had a child with a consort, Mary Ann Childs. The child’s name was Thomas R. W. Gilmour. Joseph Albert Gillmore had a long and very interesting career. There is a lot of information on him. I’ll try and talk Vicki Cooper into sharing!
The interest in this family in regards to America is the y-DNA matches that Vicki’s dad, Raymond Barrett and cousin, Adrien Gillmore have to an American Gilmore line, Family E. We are in the process of trying to figure out exactly how they are connected.
