When researching in Ireland, be aware that Ireland is divided into two localities where records can be found. In 1922 the Republic of Ireland was created independent of the United Kingdom, however six of the nine counties of the province of Ulster (Antrim, Armagh, Down, Fermanagh, Londonderry, and Tyrone) voted to remain part of the UK, which is now called Northern Ireland. This will affect where you will locate records. Also remember that England ruled Ireland for much of its history, so many records regarding Ireland may be found in English repositories.

We strongly suggest you browse through the Irish Genealogy Toolkit before you begin your research. Ireland is divided into provinces, counties, Poor Labor Unions (PLU), Townlands, etc. A good knowledge of these various divisions will greatly assist locating various records in Ireland.
