I am looking for information on Daniel Healy, b 1822, in Ireland. He married in 1846 (in Ireland) a Margaret Tierney, b 11 Aug 1825, in Ireland. I do not know where in Ireland they were from....possibly Co Mayo. They came to the US in 1848, entering in NY, then to CT for 5-6 years, then Mendota, Dakota County, MN in 1854, then settled in Washington Lake, Sibley County, MN, in about 1855. They are both buried in St. Peter Catholic Church cemetery in Mendota, MN. They had at least 6 children. I am primarily seeking information on Margaret, trying to determine if she is a sister to my g-grandfather, Thomas Tierney, of Westport, Co Mayo. Thanks!
