Having done extensive genealogy research in the northeast US in this time frame, none of the evidence presented here means much. Lots of people didn’t have birth certs, marriage records, or church records in many communities in the 1870s and 80s. Lack of evidence means little. His mother may very well have made all of this up. But there is just as much reason to believe her. Self signed birth certificate weird. But not evidence about existence of his father. #mastodaoine
