Wales:- Civil Registration

Civil Registration of births, marriages and deaths (known as "Vital Records" in some countries) started on 1 July 1837 for England and Wales.
For further information see Civil Registration in England and Wales.

Here is a map showing the 1851 Registration Districts of Wales..  The Map is taken from The Religious census of 1851 : A Calendar of the returns relating to Wales, Vol 11, North Wales. Ed. by Ieuan Gwynedd Jones, UWP, 1981

The UK BMD web site "provides 2558 links to websites that offer on-line transcriptions of UK births, marriages, deaths and censuses. A wide range of other indexes and transcriptions are also available for most counties, these may include parish records, wills, monumental inscriptions etc. "

The Registration Districts appropriate to particular towns/parishes etc have been listed on a county basis on UK BMD.

• It should be noted that Registration Districts are/were based not on parishes per se but on the official administration unit below county level.
• So in some cases the parish definition used on Genuki i.e ancient parishes, will result in one of our parishes not appearing on the above list simply because it is an ecclesiastical parish and not categorised as a civil parish.
• An example of such a parish is that of Llangamarch in Brecknockshire which was an ecclesiastical parish, so it doesn't appear on the Brecknockshire section of the above list of parishes/townships etc  under its RD i.e Builth but its two townships/hamlets of Treflis and Penbuallt do.
