I too am searching for McCarthy's from County Cork - but the names I have are a bit different that the ones posted in this string.
Cornelius McCarthy and Nora Taylor had a daughter Catherine McCarthy in County Cork, Ireland. Catherine's birthday was either April 16, 1850 or February 18, 1850. She came to the United States and was rumored to have lived with a cousin named Hannah Sweeney shortly while she got on her feet. She later married Patrick Collins, also from County Cork and they lived in Hornell, NY. Patrick Collins was born March 24, 1850 and his father was James Collins.
Does anyone have any information about these McCarthy's? If so, I would love to share information with you.
