My grandfather, David Breen, was born in Kerry, Ireland. His siblings were Henry, Michael, Deborah, Ellen (Nellie) and Honora (Nora). He emigrated to New York City in the 1890s where he was a horseshoer for the NYC Fire Dept. among others. He was very active in Irish American politics.
He died in 1931 after being hit by an automobile.
I don't know if he left from Liverpool, but I don't think so. Hope this helps. Rita
