Patrick Dwyer, County Clare, NY State, Green Isle Minnesota. My mother was a Dwyer. My great great grandfather was Patrick Dwyer of County Clare who immigrated to the U.S. in the 1840's or 1850's, first to New York state and later to Minnesota. The 1880 census indicates his age as 50, making his date of birth in the 1830's. However his wife's name was Johanna, although I don't know her maiden name. At the time of the census, they had only two sons living with them, but that does not necessarily mean that they did not have other children. This may or may not be the right Dwyer. I am still researching and am willing to share what I have.
