This is the family that descends from John Putnam of Aston Abbotts, Bucks, who came to Salem, Massachusetts in the early to mid 1640s.
The first set of Generation Reports were put together by Ed Putnam, and are basically a computer version of the initial 1908 work of Eben Putnam. As far as I can tell nothing was added or revised in this project. Later work by Rand Putnam, Matthew Putnam and myself will have much more details and additions of many, many people that Eben had no info on.
I am hoping to get Rand and Matt’s newer editions up too.
