That would be good if we were connected Linda but I have no Henry Hanrahan's at all.
Mine come from Uringford Kilkenny starting with 2 brothers Michael and William marrying 2 Tynan girls 1813 and their children I have traced to Usa and Australia and some stayed in Kilkenny. Names include Lott, Michael, William,Patrick, John, Margaret, Martin, Bridget, Catherine.
If you could find where they were from in Ireland or Henrys parents then were would have something to work on.
Heres hoping you can find some!
