In 1922 the Republic of Ireland was created and six of the nine counties forming the province of Ulster (Antrim, Armagh, Down, Fermanagh, Londonderry, and Tyrone) voted to remain part of the United Kingdom. Separate National Archives were formed for the Republic of Ireland, the National Archives of Ireland (NAI), and Northern Ireland, Public Record Office of Northern Ireland (PRONI). Similarly civil registration became, for the Republic of Ireland, The General Register Office (GRO) and, for Northern Ireland, General Register Office (Northern Ireland) known as GRONI.

Copies of many national records up to 1922 are available in both the NAI and PRONI and similarly registration records in GRO and GRONI. Records after 1922 are held in their respective offices. It is also important to note that several church dioceses of all denominations have parishes on both sides of the border  and some Ulster collections include records from Monaghan, Donegal and Cavan  as Ulster counties pre 1922.
