FreeREG stands for Free REGisters.
The FreeREG Project’s objective is to provide free Internet searches of baptism, marriage, and burial records, which have been transcribed from English parish registers. The recording of baptisms, marriages and burials in parish registers began in 1538.
This is a companion project to the FreeBMD project, which is a database of the GRO birth, marriage and death indexes from 1837 that you can search on line on the internet. This is a superb resource!
Parish Register entries will be made freely available through a search engine only. For complete transcriptions, where available, refer to the local County Records Offices, Family History Societies or to the microfilm/fiche holdings of the Church of the Latter Day Saints.
At the time of writing this, the FreeREG databases are not yet available on-line, but work is progressing.
