O'Halloran Family HistoryThis interesting name is probably a variant of "Halloran", which is the Anglicized version of the Gaelic "O'hAllmhurain", meaning the male descendant of (O) allmhurach (pirate or stranger from overseas). There are two distinct septs of this name one located in Clare and the other in Galway, where their present day descendants are numerous. The county Galway sept, whose slogan was "Clan Fearghaile abu", were chiefs of Clann Fearghaile an extensive territory near Lough Corrib. They were the original proprietors of the lands on the western boundaries of Galway City and retained a leading position in Iar-Connacht to the end of the 16th Century, for they appear in the "Composition Book of Connacht" in 1585...
