I just found this posting. Am I too late to contribute information to your book? I am a descendant of Diar Rathbun, John P. Rathbun, Martin Rathbun, Jennie Rathbun Hunt. I have a short history written by Martin Rathbun in 1917 about Diar Rathbun and his children moving to MI. I also have a copy of the family bible pages giving dates of birth, marriage and death.
