I would love it if you would send your whole file to me. Word would be best for me, thanks.
I think 1835 is correct for our Bridget Cafferty because she has children born by 1954, and the 1870 shows her and Anthony Maguire living in McLeod County. Your Bridget Cafferty is still in PA in 1870, so they are definitely 2 separate Bridgets. But it seems too coincidental that these Cafferty families both came from PA and settled in little McLeod County, MN.
I would love to see any other census information you have, or any other records you could share. Maybe there's a clue there. In the meantime, I am planning to check some death records to see if I can find parent's names, etc. I'll keep you posted on what I find. Julie
