Hi JUlie, Thanks for the reply. My GG Grandfather Thomas had a brother Robert and a brother James. We both have intermarriages with the Gilmours. One of Thomas's 6 brothers went to Australia., possibly William or Robert.Two others joined Thomas in Canada and I think 1 went directly to the U.S.A.
Have you ever heard of a location in Co Down called "Acheson Hill Head"? Thomas's bro. John was born there. Wherein Co. Down is Grey Abbey?
