From the mid 18th century the Caseys held land in the parish of Kilmurry, barony of Ibrickan, county Clare, from the Marquess of Conyngham. Griffith's Valuation records Captain Francis Casey holding 8 townlands in the parish and one townland in the parish of Kilfarboy. The Caseys sublet Seafield Lodge and its surrounding acreage to the Brews. When Francis Casey died in 1860 the property reverted to the Marquess of Conyngham who later renewed the Brew lease. Weir writes that the Honourable James Joseph Casey was one of the best known members of the Casey family. He was born at Tromeroe in 1831 and became Australia's first Minister of Agriculture. Ninety acres of the farm and lands of Tromoroe and Quilty, parish of Kilmurry, barony of Ibrickan, the estate of James Casey, were advertised for sale in January 1866 and in February 1871. Members of the Casey family still owned small holdings of land at Quilty West in the 1870s. 92 acres belonging to Francis Casey were vested in the Congested Districts' Board on 31 March 1914.
