James Anthony McDermott of Ramore married Mary Agnes Blake of Cregg Castle in the early 19th century and this may explain why the McDermotts held Cloghanower and Mountross in the parish of Killeany, barony of Clare, county Galway. Their 822 acres in the parish of Killeany was advertised for sale in 1856. James McDermott was one of the principal lessors in the parishes of Killimorbologue, barony of Longford and Clontuskert, barony of Clonmacnowen, county Galway, in 1856. In 1873, Anthony Joseph MacDermott of Ramore married Liza, daughter and coheir of Patrick Crean Lynch of Clogher, county Mayo. Over 3,000 acres in county Mayo belonging to him and others was vested in the Congested Districts' Board on 13 Mar 1913. The Ramore estate amounted to over 3500 acres in the 1870s. In 1906 James McDermott owned about 250 acres of untenanted land and the mansion house at Rathmore, valued at £39.
