I'm trying to find information on John Tierney, b. Minnesota in 1868 to Bridget (Dillon) Tierney and Michael Tierney. Michael died in 1868, buried in Jessenland, MN. Bridget and son John are listed in the 1880 and 1900 Federal Census in Green Isle, MN, but drop off the map after that. John was still single on the 1900 census, and I suspect that Bridget died before the 1910 census. Also, one census record states that she was the mother of three children, but I haven't found any info on them. I suspect they died young. She came to the US in 1860, whether she was married at that time or not, I haven't discovered yet.
