Just came across your posting of 2002! I was interested in this as my maternal great grandfather was a Samuel Getty Drennan b: 1847. I believe that he worked on his father's (Maxwell Drennan) farm in Ballyearl. Antrim. I've often wondered where the Getty came from. I didn't think it was from his mother as I think she was Agnes Gaunt. Have you had any success with your investigations?
