In 2005 the Ulster Historical Foundation was commissioned to compile a database of records for Newry and Mourne District Council as well as a guide to carrying out family history research in Newry and Mourne. The records digitised included the Householders Index to the area, 1803 agricultural census for Newry parish, deeds and other documents from the Kilmorey and Crossle collections in the Public Record Office of Northern Ireland, Newry and Mourne wills, 1727–1858, and names for Newry from the 1900 Belfast and Province of Ulster Street Directory. Over 14,000 individual names were indexed as part of the project. The Ulster Historical Foundation was subsequently asked to produce a promotional leaflet advertising the website and online database.
Newry Museum, based in Bagenal’s Castle, a restored 16th-century fortified house, holds an extensive archive collection containing material relating to local history and genealogy in south Armagh and south Down.
