||Wilson refers to Grenan's-town as the seat of Mr. Dalton in 1786. In 1837 Lewis describes Grenanstown as the seat of Count D'Alton. The Ordnance Survey Name Books note that James Williams was leasing Grenanstown but that it was occasionally the residence of Count D'Alton. At the time of Griffith's Valuation James Williams occupied Grenanstown. He held the property from Count D'Alton and the buildings were valued at £19.11 shillings. The National Inventory of Architectural Heritage states that Richard Dalton Williams (1822-1862), poet and Young Irelander, lived here as a child. This house was later the property of Henry Eustace, a member of the Robertstown, county Kildare family. It is now a ruin.
