Barbara and Monica,
I have done a lot of searching. The "names" site is exceptional! I also have an ancestor whose sister was Grisel (Grace). Now I understand how others concluded she was the same person. I learned quite a lot from the maps but never did find East Middle. I can see the Parishes are small.
I have exhausted IGI and Scotlandspeople. I did find a record on IGI for an Agnes Blyth baptised before 1790 in East Middle and married to John Scott abt 1801. I am assuming the abt 1801 is because the record I found was banns (13 Apr 1801). The person who recorded the information made the same assumption I did about east Middle as birth place.
Anyway, with all my searching, I had forgotten that Nancy's mother was supposed to be a Muir. The baptism in Wilton had a mother ...Isabel Reid whereas the baptism in Ancrum has no mother named.
I know I can't prove it likely but does this sound reasonable:
Nancy Blythe was born Agnes Blyth and baptised on 24 Oct 1783 in Ancrum. Probably born about 1 Oct 1783. Banns read in Kirktown 13 Apr 1801. Marriage perhaps later in April or in May. Nancy (Agnes) would have been 17 1/2 when married.
I don't think being married before 18 would have been unusual. Is baptism in Ancrum, growing up in Kirktown and meeting husband in Cavers reasonable?
I think I just may have it!!
Thanks so much,
Jan
