Geoghegan/O'Neill (Bunowen)

Art Geoghegan of Castletown, county Westmeath, was transplanted to the confiscated O'Flaherty lands at Bunowen, parish of Ballindoon, barony of Ballynahinch, county Galway, by the Cromwellian Commissioners. During the 18th century the Geoghegans became Protestants and at the beginning of the 19th century changed their surname to O'Neill. The Geoghegans were originally one of the septs of the south Uí Neill. John Augustus O'Neill, Member of Parliament, succeeded to the estate in 1830 but after the Famine he was in severe financial difficulty and sold most of his estate in 1852 to Valentine O'Connor Blake of Towerhill. At the time of Griffith's Valuation a Thomas Geoghegan held a townland in both the parishes of Moyrus and Ballindoon, barony of Ballynahinch.
