Kate "Kitty" Hargadon was from Carrownawaddoo, County Sligo, Ireland and was the youngest child of Patrick and Mary Hargadon--her mother's maiden name was something like Coyan or Cogan--difficult to make it out on her birth certificate. Her father was a day laborer.
She was 17 and was on her way to join an older sister in New York (the family consisted of at least 4 daughters, Mary Ann, Bee, Margaret, and Kate) and to find work as a domestic. She was seasick most of the trip and couldn't climb the ladder to the boat deck--Mary Delia Burns stayed back with her and both died while their friend Margaret Devaney entered a lifeboat and survived.
I hope that tells a little of what you wanted to know.
