We know her sister Elizabeth A. Fitzgerald, married Michael Buckley about 1873 and I have 5 children for them. She took those children back to Ireland to visit her parents about 1890, and the children went to school there for one year, returning in 1891. Michael Buckley worked on her father's estate before they were married, and family lore said it was a large estate.
I am looking for the Fitzgerald family in Ireland. Elizabeth (Fitgerald) Buckley had a son named Cornelius, and maybe he was namesd after her father.
