I'm looking into him harder now, thanks, my only reason for doubting that is that the 'scribe' wrote S at the end of a line and I think it would have looked weird to write Griffing after without breaking the name to the next line. They might not have cared though. Ebenezer Smith has mild connections to people with last names like Gillum and Dickinson and you see those names pop up related to Abigail Griffing's will, which was another reason I thought it was that guy.
I'm still digging through probate records but I'm not finding a smoking gun. At this rate I may eventually pay someone to try to figure this out. Sigh. At some point.
