At the time of Griffith's Valuation Lieutenant Colonel Maberly was a lessor of property in the parish of Moore, barony of Moycarn. In the 1870s Colonel William Maberley is recorded as the owner of over 800 acres in county Roscommon and over 2,500 acres in county Tipperary. He resided in London at that time. He appears to be the Colonel William Maberly who was secretary to the English Post Office and the superior to whom the author Anthony Trollope reported in his early years in the postal service. Colonel Maberly's county Tipperary estate was in the parish of Kilmore, barony of Upper Ormond. Part of it held by fee farm grant by the assignees of James O'Meara of Nenagh, was advertised for sale in July 1851. Colonel William Maberly was married to a niece of the 2nd Baron Dunalley.
