Amos Porter was my g-g-g-g-grandfather. I have a lot of data on his descendants in the Upper Ohio Valley.
Amos Porter and Allen Putnam were brothers-in-law. Jointly they owned one share in the Ohio Company. Later each had a homestead in Washington Co. I have visited the site of the Porter homestead at Lower Salem, and have located the grave of his mother Anna Bradstreet.
I have searched unsuccessfully for the relationship between Allen Putnam and Rufus Putnam. Would appreciate any help you can give me on this.
