Hi David,
No my Mary Ann died as a single woman in 1835. The only other option I have would be a possible connection with the Chaytors / Charters of Kirby moorside Yorkshire. I found another Mary Ann Chaytor born in 1803 Easington Yorkshire. Born to a single woman Mary Charter. Easington is not far from Skelton Yorkshire. However the death record of my Mary Ann is very definate that she was 29 years old when she died. ie birth date must be around September / October 1806 - hence maybe the Darlington mob. All a mystery to me.
Anyway thanks for your information.
Regards - Paul.
