Description Cloonboony is a five-bay single-storey over basement house on a U-shaped plan, built c.1790, having two two-storey returns (boi). Cloonbonny House was originally built by the Longworth family as a dower house to Glynwood House (O’Brien). Edward Marsh was resident at the time of Griffith’s Valuation (publ. 1854) when the house was valued at £11 and was held from Francis Longworth. The Johnson and Byrne families have occupied the house from 1869 until the present day.
