Re you're question about Cornelius Hourihan(e).
My grandfater was Cornelius. I believe he first went to New York, then married Rose Brigette O'Flynn and they moved to Massachusetts, settling in Milford. They had William, Daniel, Francis, James, Mary, Rose and my father John T.
My father had Patricia, Diane, Nancy, Sheila Dennis, Cornelius and myself, John Jr.
Hope htis helps
