So there is a profile I've been working on putting together for a while now, Jacob William Carrier. His parents, as I've found, are Burton/Barton Carrier and Amelia/Aurilla (maiden name unknown) Carrier.
Here's the thing. This guy wasn't against lying, and the places these names have appeared are where he'd self-report his information. How do I know he wasn't against lying? He got married while married and told people his first wife was dead as were the children. I believe that means it's not unlikely that he himself would be prone to lies.
He might not even be a Carrier, for all I know. Or maybe his mother's name really is Amelia/Aurilla/Aurelia, and his father is a Barton/Burton Carrier, but he's an illegitimate child and his parents never wed. I don't know. What I do know is that aside from being in the news back-in-the-day for his shenanigans, his prison records, and being listed as the father of his children, there's no proof his parents existed as he said, or that he even existed.
I guess the first step really is to find his mother or his birth record before his parents can be found. Maybe some other way. I've tried looking through wills and the like, finding nothing. Maybe I'm missing something. If you find anything, please, let me know!
