Hi Monica,
Yes, the wives names, and the destinations. This line migrated to Canada's east coast - New Brunswick
I noted the errors/mis connections/ inconsistencies on Ancestry too. I did as much as I could at the National Archives here in Ottawa and trailed back as far as I could to/in Scotland.
I am fortunate as my mother is #10 in a line of 19 children and some of the older siblings have/had good memories and stories from my g grannie who recorded stories from her mom and grannie (my Agnes) in her journals (along with some recipes!).
Because of the dates I''m working with here, I expect to use caution in securing a line. Maybe I'm being too lofty.
I feel pretty strongly that these people were in the Kirkcudbrightshire area because of my Agnes Tait b. 1799 (Roberts Daughter). She married a Cuthbertson from the same vicinity.
I think I'm just going to have to head to the UK to sort this out

Thanks again
Kind regards,
Misha
