My Lusk family lived in Banbridge, N. Ireland. Grandfather, Joseph Lusk, married Grace Hampton in 1887, immigrated to U.S. in 1888. He had a cousin who came to this country sometime around 1905 - 1910. Believe his name was John, and that he went out west. Nothing further ever heard from him. My grandfather's parents were Johnand Rachel (Corry) Lusk. I believe my grandfather's grandparents were George and Isabella Lusk. Does this tie in with your Lusks?
