Thanks for writing. It is entirely possible that I have a generation missingbetween Christopher and Jonathan. The timing between their births certainly is sufficient to fit in another generation of Pinkhams. However, the source I have been using is the book "Richard Pinkham of Old Dover and his Descendents" by Charles Nelson Sinnett printed in 1908. In Sinnett's book Jonathan was clearly the father of Christopher. Abigail Bunker is listed as the wife of Stubael Pinkham. Stubael was Jonathan's brother. Abigail's parents are listed as William Bunker and Mary Macy. I would be very interested in sharing information. My e-mail address is email@example.com. If you would care to e-mail me and give me an address I will be glad to send you any information that I have. I would be very interested in seeing your source information on John Pinkham.
