Ireland. The O’Learys were a Cork clan. In the 12th century they were recognized as the hereditary wardens of St. Fachtna’s monastery in Ross Carbery. Later they were pushed north and settled in an area south of Macroom called Inchigeelagh. Here they ruled as chiefs under the MacCarthys of Muskerry. They appeared in the 16th century as a titled and wealthy family.
They lost out during Elizabethan times in the Nine Years War. For this their chiefs were attained and their lands parceled out. But because of the remoteness of their territory it was never carried out and they remained safe for a while, until the Cromwellian confiscations. In 1642 sixteen O’Learys were attainted, including Connor O’Leary of Carrignacurra and Auliff O’Leary of Cunnowley. The last O’Leary lord of the old Gaelic order was Donal MacArt O’Leary who died in 1657.
