I'm looking for information concerning the Donlan (Donnellan) line from the Silvermines in Tipperary. I have traced my family back through Denis Donlan (b. 1860) who was the son of James Donnellan and Mary Fogarty. I commissioned a search through the Tipperary Family History Research Center and they found his birth record as well as multiple siblings (Mary, Patrick, Catherine, John, Johnanna, Thomas and James), but could find no records of marriage or birth for either James Donnellan or Mary Fogarty. Any help would be appreciated.
