I am researching the Nagle line of my family. My 3x great grandfather's name was David Nagle. He was born in Ireland in the early 1800's. He was married to Mary Foley. The had 4 children Hannah, Nellie, John, and James. John was b: 1840 and was my 2x great grandfather. He and wife Margaret McCarthy settled in Dansville, NY around 1880. Any Help on this line would be great. I know that many Nagles still live in Dansville.
