Since my original post, I've discovered that Elizabeth isn't really a Pinkham, but a Davis. Pinkham was the name of her mothers second husband, Richard Pinkham. Elizabeths father was actually Eleazer Reuel Davis, who died when she was young.
I have the ancestry of both of Elizabeth's parents. I'm decended from William & Elizabeth Willy's son, William Willey Jr. who married Mary Downs.
Do you have the Dorr ancestry? I have a great deal on this line. Ebenezer Dorr Jr. was one of 4 other men that met with Paul Revere and helped spread the warning that "The British were coming". Seven of his eight sons served in the American Revolution.
Can any of this help you out any? I'll be glad to share what I have.
