For the purposes of registering Births and Deaths, the current Bath and North East Somerset Unitary Authority area was divided into a number of Registrars' Sub-Districts, which could cover anything from part of a large town, up to a group of several dozen rural parishes. The boundaries of these areas have changed frequently over the years since 1837, and as a result many birth and death records have been transferred between different register offices. The map below shows the area covered by the Bath and North East Somerset Register Office where all Birth records are now amalgamated and held.

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.
This page lists ALL Birth Registers held at the Bath Register Office.
