"Ballykeevican: A central townland. Bounded on the North and East by Rockingham Demesne. South by Radiveen and Keelogue and on the West by Kilbryan… Only one farm possessed by Tobias Payton Esq. whose residence in this townland is called Oatlands House. The soil is very good‘ [John O'Donovan AL1837].
"On the south side of Lough Key is the demesne of Rockingham, the beautiful seat of Viscount Lorton, who has greatly improved this parish, as well as his other estates. Here is also Oatlands, the seat of T. Pearson, Esq. (typo: Peyton) [Lewis's Topographical Dictionary of Ireland, 1837].
At the time of Griffith's Valuation, Alicia Peyton was leasing a house valued at £13 at Ballykeevican, barony of Boyle, from Viscount Lorton's estate.
Oatlands is now Lough Key House guesthouse.
