My grandfather was JAMES BURKE, who served in the military in Dublin in the 1880's, according to his family. He married MARY JANE CORLETT, whose father was a seaman from the Isle of Man. They lived for a few years in Lower Campsie, outside of Londonderry, working for a Major Quinn. They emigrated from Londonderry in 1908 to Alberta, Canada. bringing their large family with them. Searching for their origins - any help or hints greatly appreciated!! Dorothy Gladish
