Public Record Office of Northern Ireland (PRONI)

As the official place of deposit for public records in Northern Ireland, PRONI holds literally millions of documents that relate chiefly, but by no means exclusively, to Northern Ireland. The records cover the period from ca. 1600 to the present day, with a few dating back as far as the early 13th century. Records fall into three general categories: government departments, records of ministries such as Agriculture and Finance; non-departmental public bodies, such as courts of law and local authorities; and private deposits by individuals, churches, businesses and institutions. The vast collection includes tax, and estate records, surviving Church of Ireland registers, Griffith’s Valuation records, Tithe Applotment Books for Northern Ireland, wills, leases, and Valuation Office records for Northern Ireland.
