My gg-grandfather is Patrick Hanrahan, from Ireland, and he probably came to the US in 1857. He married Mary HURLEY. The settled in Steuben Co., New York (Thurston, Rathbone, and Corning). There were three Hanrahan farms in the area, we suspect the other two belong to John and James.
In the 1900 Rathbone, Steuben Co., NY census Patrick had Living with him his grand-daughter, Mary JOICE. and in the 1892 Rathbone census, He had Hannah JOYCE living with him. Patrick was born about 1826, Hannah Joyce b. about 1859, and Mary Joyce about 1892. If any of this sounds like it may matche your research, please let me know. I'd be willing to share information on these families.
