Well, you have just cracked the case for me! Joseph's family lived in the Dover-Foxcroft area of Maine in 1880. The town of Dover, ME is mentioned on some of his MA marriage records. He had two sisters in 1880 and one of them was Josephine born 1861. When I looked at Peter Libby on the 1910 census of Foxcroft his wife is "Josie" born c1861. I will check their marriage to get her maiden name, but I'm already certain this is indeed the correct Joseph. I wonder if his wife in MA ever found out about his seven marriages and at least four abandoned children? Probably not. Thank you again for all of your assistance! I really appreciate it. Can't wait to pass on this info to Joseph's great grandson and another relative I'm assisting. They will be so happy to know this can now be proved.
