Callaghan/Calahan and Berrane/Berane

Looking for information on Michael Callahan/Calahan 1821-1903 born in Eyrecourt and died in Kiltormer I think and his wife Maria Berrane/Berane 1844-? Also, Bernard Berrane 1821-1880 and John Joseph Callahan, brother of Michael. Any Callahan or Berrane reference would be helpful. I've been to this town and spoken to the parish priest to no avail. The Callahans/Berranes moved to Kiltormer and raised a large family, including my grandfather Michael Aloysius O'Callaghan 1876-1946. Michael Aloysius moved to Nenagh and married Bridget Delia Luttrell and had a large family. John Joseph O'Callaghan stayed in Kiltormer and married Rosanna Davies. One of their children, Maureen married a John Joseph O'Halloran and they raised a family of four in Kiltormer. Brien O'Callaghan, brienoc@att.net, and cell: 203.788.6993, Bethel, CT, USA.
