My HEARLIHY ancestry begins in Boston, MA abt 1835, when Ellen DRISCOLL emigrated from Cork, Ire. as an infant. She m Dennis Jeremiah HEARLIHY; they had abt 8 children between 1858-1882. Their first-born, Mary HEARLIHY, m Lawrence CURTIN in NYC abt. 1890. Is my line linked with your own? I find the occurrence of both Herlihy and Curtin rare enough to pique my curiosity.
