Hello Diana:
How nice to hear from you--John and Eliza are my great-grandparents as well.
I descend from them through their son Joshua, who was married to Rebecca Crow. I do have more information and some pictures that I could scan and send you if you will give me your e-mail address. It might take some time for me to scan the pictures, but I'll try to get some of the written information to you soon (by this weekend, I hope).
