For the purposes of registering Births and Deaths, North Wales was divided into a number of Registrars' Sub-districts, which could cover anything from one town, up to a group of perhaps a dozen rural parishes. The boundaries of these areas have changed frequently over the years since 1837, and as a result many birth and death registers have been transferred between different register offices.
The following listing refers to the birth indexes that have already been placed on the North Wales BMD website.
Click on the name of a sub-district to see a list of the parishes / places it covered.
This page will be updated each time new records are added to the database, and recent additions will also be indicated on the Updates page.
