Thank you to everyone who has been kind enought to take a look at my Moses Ashby thread. I hoped he might be the link to my actual brickwall which is this:
Thomas and Elizabeth Ashby are my husband's 3xgreat-grandparents. They had 6 children, the first three were baptised in West Wycombe and the later three in Radnage. I believe Thomas married Elizabeth Stealion on 2.10.1810 in Saunderton. Their witnesses were Moses Ashby and Sarah Ashby (Pallotts marriage index).
Moses and Sarah are the children of Thomas and Ann Ashby nee Hore of West Wycombe that have cropped up a lot in the Moses Ashby thread. Thomas is not. At least, I have not found a baptism for him that links him with this couple. But clearly he is linked somehow albeit sibling, cousin or same named friend. Moses is his witness, and he names a son Moses. Moses father is Thomas, his grandfather is Thomas. There ought to be a brother called Thomas but there isn't. There are several trees online that have a Thomas attached to this family but there is no evidence to back it up.
Moses marries a Sarah Hearn ten days later, on 12.10.1810 in Penn where the couple live. They baptise a child, Mary, in 1813 in Chepping Wycombe Wesleyan Methodist Chapel. The database doesn't have any other records for this couple, or any other Ashbys that connect to this tree. Moses disappears from the record after the baptism of two more children in the early 1820s, Ephraim and Lydia. I can't find his death, he's not on the 1841 census and I can't explain the huge gap (about 10 years) between the first and second child.
My theory is that Thomas is either a son of Thomas, brother of Moses, who was unbaptised or his baptism is missing/elsewhere. Or he is a distant relation and might be the son of David and Martha Ashby of Fenny Stratford, north Bucks. Notably, Thomas's firstborn was called David.
Any ideas would be gratefully received. Thank you.
