Welsh genealogy records

The Welsh census

The Census for Wales is available for researchers to explore in the following years: 1841, 1851, 1861, 1871, 1881, 1891, 1901, 1911 and 1921. You can access these online (£) at Ancestry and FindMyPast, or free of charge at FamilySearch centres around the world. Note: The 1921 Census is only available online at FindMyPast, but is also free to view at the National Library of Wales, in Aberystwyth.

Births, marriages and deaths for Wales

National Library of Wales is home to copies of the indexes of Welsh births, marriages and deaths from 1 July 1837 onwards (please note that the library does not hold or issue certificates). At the library, you can access microfiche copies of the indexes from 1837 to 1998, and also access FindMyPast and Ancestry online indexes free of charge.

North Wales BMD is another useful resource, an ongoing project by Welsh family history societies to make available the indexes of births, marriages and deaths from the local register offices of North Wales (as opposed to the GRO indexes) from the start of civil registration in 1837.

Pre 1837 parish registers

Welsh baptisms, marriages and burials recorded within church records are extremely useful for tracing your family tree back before the start of civil registration.

Before the start of civil registration, you will find Welsh baptisms, marriages and burials recorded within church records. The registers of these original records are kept by county record offices around Wales, which are listed at National Library of Wales here. National Library of Wales has over 500 parishes on microfilm on open access, as well as transcripts and indexes of various parish registers made by family history societies, and online collections accessible via Ancestry and FindMyPast. Bishops Transcripts, wills and marriage bonds are also available, to replace or supplement the information found in baptism, marriage and burial records. 


Wills/ Ewyllysiau at the National Library of Wales allows you to search for wills proved in the Welsh ecclesiastical courts before 1858.  If you have a readers’ ticket to the NLW you can log in and view the will online.

Carmarthenshire and Bangor Wills Index Cards were released by Ancestry in August 2022. The database is derived from index cards related to wills filed in two Welsh regions. The index entries for the area of Bangor, numbering almost 31,000, are dated between 1885 and 1941, while the 13,000 entries for Carmarthenshire are dated between 1920 and 1941. The index is alphabetised by last name and provides information about when and where a will was filed, however, the index doesn't include a link to an image or the text of the will.
