Re your other point on ages - it wasn't required that that time to note with whose permission in case of minors (actual ages would not be noted until early 19th C) but a 17/18 yr old marrying would be noted I think especially as his place of origin was.

I have only checked the Bra baptisms upto 1714 so not sure of any children but the first (and only ?) baptismal entry that gives Ann Moore as mother is in 1734
