Just happened to stumble upon your message, I am only now attempting to research the Horan side of my family history. My father died when I was young and our family pretty much lost touch with the Horan side of my family. However, an interesting side note, my mother's side of the family comes from Tipperary, Ireland (Carrick on Suir). My Great Grandfather's name was John O'Shea and he was married to a Mary Walsh, probably in the 1858 year, my Grandfather Joe Shea immigrted to New York in 1913.

If I come with any Horan information, particularly if our family is from Tipperary I'll let you know.

Good luck with your family serch.
