Some of the major collections held by the Archives are the 1901 and 1911 Census, and both the Tithe Applotment and Griffith’s Primary Valuation, and wills. These are considered census substitutes due to the destruction, for the most part, of Irelands census records from 1821 until 1901. A list of researchers is available.
