Proni is the Public Record Office of Northern Ireland which has many records and archives of interest to family historians, genealogists and local historians.
Their collections include the Ulster Covenant which was signed by 237,368 men, and the Declaration by 234,046 women. Another interesting resource which is viewable online is the Freeholders’ records collection which contains the names of people entitled to vote, or of people who voted, at elections.
Perhaps the most useful are the Will Calendars which is a fully searchable index to the will calendar entries for the three District Probate Registries of Armagh, Belfast and Londonderry, with the facility to view the entire will calendar entry for each successful search. The database covers the period 1858-1919 and 1922-1943. Part of 1921 has been added, with remaining entries for 1920-1921 to follow in the near future.
