The only info I have is: Katherine's place of birth was Ballyhillin, parish Clonmany. Her father was James McGaffigan. She was married to William Kenney and had seven children with him. Barney was her brother and she had two half brothers, John and Pat. She also had a half sister, Ellen. The story is she came to Castle Garden New York when she was twelve years old. That would be 1871-1872. Hope this helps.
