In the 1841 census my greatgrandfather shows up with two more sons Samuell and John. So, I do have those names. They don't appear anywhere else. I had a family tree given to be by my father that listed my grandfather back to Cornelius and then to a John Hatton that died in London. No dates etc. I tested with a cousin descended from another son of Cornelius and we are a perfect DNA match but rare.
We have no other DNA perfect DNA matches. I think Cornelius was on a ship's crew possibly. He left Charles a Cat-O-Nine-Tales. Unless that was used in some other way?
