Jack, this link has been around a while. Its based on original research done by my Dublin librarian cousin in the 1950's . This particular history ends in the 1700s. I suspect due to the fact the person who uploaded it discovered the original research led directly to our Hanley branch in Carrowmacbryan.
Beyond 1700 many Hanley branches can insert themself in, as was obviously done here. The hard part is do what my researcher cousin did and trace a single father son lineage all the way back to Brian Boru, which she did.
Way back when the Hanleys, actually O'hAinlie's were the equivalent of a palace guard to Kings of Connaugh and to the O'Connor sept. At that time, to consolidate power Brian Boru inserted his genes into every Irish clan he could. Many Irish names go straight back to Boru due to his profligacy. In a manner of speaking, he made nearly all the Irish who originated in Ireland distant cousins to each other.
A notable exception are rather recent newcomers to Ireland. All names with Fitz in them come from French-Norman invasions of the 1200s, which is way after Boru's time. A lot of these Norman originated names, like Guiness are now considered Irish, but not to folk who research their roots to and beyond Boru. The poets Yeats is a very recent immigrant to Ireland, he was a 2nd generation born in Ireland.
IMHO, The wanna- be Irish are occupiers who never bothered to go home, and IMHO have sullied the noble heritage of those Irish families that pre-date Brian Boru.
