At the time of Griffith's Valuation, Heathlawn house, valued at £31, was occupied by George Saunderson. In 1837, Lewis records it as the seat of M. Monahan. Slater, in 1846, also notes it as the seat of Michael Monaghan. In 1906 it was the property of James H. Monahan. In 1783 Taylor and Skinner, and Wilson, writing in 1786, noted Heathlawn as a seat of the Hamilton family. It is no longer extant.
