My ggggrandfather was Jeremiah Quinlan, born 1825. He had a daughter Mary, born in County Kerry date unknown. I think his wife was possibly Margaret Maher. They traveled to the US when Mary was 13. Jeremiah died on June 12, 1873 in Pennsylvania.
Mary married John Dundon (born 1840 in County Limerick, died 1878 in Pennsylvania). They had 6 children: Charles, Patrick, Mary, Jack, Margaret, Ann.
