The Hickson Estate, an area referred to as tClucan (anglicised Tullighan) by T M Donovan in his Popular History of East Kerry, was the property of George A E Hickson of Woodville House, Ballyegan, Co Kerry. It was sold in 1906:
Sale of a Trinity College Estate. The sale of the Hickson estate, situate in the Clogher district some three miles from Castleisland, constitutes the first satisfactory negotiation of a Trinity College estate in this part of Kerry since the introduction of the new Land Act of 1903 … great credit is due to the Rev McCarthy O’Connor, parish priest of Clogher, for carrying through the negotiations.
In 1910, in the court of the Land Commission, the lands were identified as Coolgarriv, part of Ballyegan, part of Cragg, part of Mweenalaa, part of Nohoval South, barony of Trughanacmy.
