Hi Sarah,

Meet the Ancestors, I suppose? - I too have the same photograph as you have in the Family Bible. But do not believe I have any other photo's from the Martin side of the family.
So were Harry Martin (your GGF) and Bertha V Martin (my GM) both Dorothy's Children or was my GM Jane Martin's?
I have no idea, but a good place to start. (My Grandmother always called RHG Harry, unless she was annoyed with him, when he would get his full title HENRY!!!)
