Hi Tim
I have Ruth's book and it is an excellent piece of work that she has done. I didn't see a Thomas married to Sarah Shimmin. The book contains info on The Moore families from Balldromma Lonan, Ballamore Patrick, the Abbey, and Pulrose. It is also invaluable for anyone researching the Christian Family.
Ruth also sent some trees of the Skillicorn, Kissack, and Moore families which she had put together in 1994. How did you get in touch with her, the last I heard she was in a nursing home in Australia.
