My Mugans are also from Castlebar, but I can't figure out how the Castlebar Mugans are related. My grandfather John Mugan was baptised 1878 in Castlebar. His Parents were Patrick Mugan (1831) and Anne Loftus (1841) - they were married in Islandeady. The 1911 census shows Anne at Deergrove Castlebar with an apparently unrelated Patrick Mugan next door. According to my mother, my Patrick may have originated from Westport.
