Andrew, I thank you for your contact. I must admit, until yesterday, I had no information on Thomas of the Black Horse, then I read that he was a son of Thomas and brother to Goin. I was suspicious of that information.
My info on Thomas and Eliz Kyle spans 9 generations as a result of secondary families and I would love to swap data with you but am reluctant to post it all to a message board. If you would send your e-mail address to me at firstname.lastname@example.org, I'll forward what I have to you.
