Donna, you would get people hunting through their files if you could include any locations or children/spouse names. Children are often named after ancestors so someone with a Thomas who has a father the same name as your Thomas' son might get in touch with you. Just a hint.
My GG Grandfather was John Milligan b.1804 near Ayr,Scotland. He had an older brother named Thomas. Their father was Roger Milliken from Co.Down,Ireland.
I am searching for Roger's father who may have been named Thomas. I' be glad to share what I have with you.
