Yes, your people are connected to my people! Betsey Maria Blighton was a younger sister of my Hiram C Blighton. He was my 4x ggrandfather.
The only bits of info I've found re Hiram are from various genealogy websites and I don't take that info as any kind of proof for him - just clues.
Do you have any information about the Blighton Grandparents of Hiram and Betsey? Something that I noticed - did Betsey really marry in 1826? She would have only been 14 years old. Isn't that even abit too young, considering the times?
