Ian, Dates of the published Griffith's Volumes for Queen's County are 1850-1851. The Revision Books (annual updates) begin in 1855. The annual updates, now held in the Valuation Office in Dublin, were never published, but they have been microfilmed and can be borrowed for use at a Family History Library (LDS) in your area. These books show the year when a property changed hands, either for Lessor [landlord] or Occupier [head of household], and they could help solve your problem if the published books do not..
