The Phibbs family acquired an estate in Kilmacowen in the late 18th century. The estate was based around Seafield House which was built by William Phibbs, c. 1798. A later house, also called Seafield, was built in the townland of Lisheen, nearby. The estate, which was held under fee-farm grant from the Merediths, was offered for sale in the Landed Estates Court in January 1877. The family also owned a dower house at Coradoo, near Ballinafad, County Sligo as well as property in the barony of Boyle, county Roscommon. In the 1870s the Misses Phibbs, of Drumcormack, Boyle, held over 150 acres in Roscommon while William Phibbs was the owner of over 800 acres including lands in the parish of Kiltullagh, barony of Castlereagh. Earlier, in June 1852, William Phibbs had offered for sale over 300 acres of his Roscommon estate as well as over 2000 acres of an estate in county Westmeath, in the Encumbered Estates court. In 1867 oyster beds and houses in the city of Dublin, associated with the estate of Edward Joshua Cooper, were offered for sale in the Landed Estates Court. In 1906 Catherine Phibbs is recorded as the occupier of property in the townland of Lisheenacooravan, barony of Carbury, including a mansion house. The Congested Districts Board acquired almost 1400 acres of the estate of Owen Phibbs in the early twentieth century.
