I believe this John Quirk is my GGGGrandfather. Born ireland in 1800, married Katherine Dormer.
My GGGrandma is John's daughter Mary, born in Beetown, WI in 1845. There was a sister born in Cresco, IA in 1852, but I have been unable to find any records from Cresco. Another sister Margaret married John Cahill. I believe the Cahills were in SD.
I would love to hear of any information you could add!
