Freeholders' records are held within the Public Record Office of Northern Ireland (PRONI). The PRONI freeholders project indexed and digitized approximately "5,500 sheets from pre-1840 Registers and Poll Books." These Freeholders' Registers and Poll Books are often used to substitute records lost in the 1922 Dublin fire.
Freeholder Records can be searched by name and address. Visit the PRONI FreeHolder's Record webpage to begin your search.These records hold land ownership information to include the name and address of the freeholder. The researcher may also uncover a description of the freehold and its value. If leased, name and address of the landlord may also be provided. From a genealogical standpoint, the researcher may verify the occupation and religion of a freeholder ancestor.
The website specifies that some of the records are in their original form, while others are transcripts or manuscripts.
