I have that Hamilton family in my tree, David & Mary (Gavel)Hamilton also have a son named Thomas Kirby Hamilton, and he married a Mary Abie Haynes, who is my great grandaunt. I would LOVE to see your tree if I could.
Mine is the Haynes family tree, but I also have another (main)tree I work on more frequently.

I don't know much about about the Hamilton's at this stage, but I am certainly willing to share all I have.
Hope to hear from you
