Naghten (Thomastown)

The Naghtens or O'Naghtens were one of the old Gaelic families who managed to retain some of their former lands after the land settlements of the late 17th century by conforming to the Established Church in the 18th century. The Naghten estate was in the parish of Drum, barony of Athlone, county Roscommon. The Naghtens intermarried with the D'Arcys of Houndswood, county Mayo, the Burkes of Tiaquin, county Galway and the Dillons of Johnstown, county Roscommon. In 1828 Thomas Mahon Naghten was a member of the Grand Panel of county Roscommon. In the 1870s the Naghten estate amounted to 4,829 acres in county Roscommon. Malachy Naghten was described as an insolvent debtor when two properties belonging to him were advertised for sale in the mid 1850s. He was one of the parties in a case, Keogh v Naghten, in the Court of Chancery. It is not clear if he was closely related to the Thomastown Naghtens.
