Thomas Heagerty's wife was Elizabeth McAuliffe, one of 8 children of Maurice McAuliffe & Margaret Cowan McAuliffe. My Greatgrandmother was Susan McAuliffe, one of Elizabeth's sisters. Maurice was born in Doneraile, County Cork, Ireland 12/4/1847 & died in Baltimore 1/11/1933. He came to the USA with his brother David & sister Francis. I have additional information on the family & am interested in any info you may have.
