Effective research in church records requires some understanding of your ancestor’s religion and the events that led to the creation of church records.

In 1531 King Henry VIII declared himself to be supreme head of the Church of England, which became the state religion. Individual church units, called parishes, controlled poor relief, military conscription, and some law enforcement and taxation.

The Church in Wales (Church of England) is also known as the Established, Anglican, or Episcopal Church.

In 1922 an Act of Parliament disestablished the Church of England in Wales. The Church in Wales became independent from the Church of England.

The following major events affected Welsh church and chapel history and records:

1531	Henry VIII recognized as head of the newly created Church of England. All ties with the Pope and the church in Rome severed.
1538	Thomas Cromwell ordered all parish ministers to record christenings, marriages, and burials.
1563	The Test Act excluded Roman Catholics from governmental offices and fined them for not attending Church of England services.
1588	Bishop William Morgan translated the Bible into Welsh.
1598	Parishes began sending annual copies of parish registers to the bishop of the diocese. These are called bishop’s transcripts.
1598	Parish registers were required to be kept on parchment and previous registers copied onto parchment.
1606	A law forced Roman Catholics to be baptized and married by Church of England clergy and to be buried in the churchyard. Many complied in regard to burials, but they continued to baptize and marry in secret.
1639	The first nonconforming church in Wales was the Independent congregation in Llanfaches, Monmouthshire.
1642–1660	Civil war caused political and religious upheaval. Parish registers were poorly kept or destroyed.
1645	Some Independent congregation members at Llanfaches left and formed the first Baptist church in Wales at Llantrisant and Llangwm, Monmouthshire.
1662–1688	This was a period of intense persecution for nonconformists. Many were jailed or lost their property, especially members of the Society of Friends (Quakers). From the 1680s, many Welshmen emigrated to Pennsylvania. The Acts of Toleration were passed in 1688, allowing nonconformist sects to worship freely.
1695–1706	A tax was assessed on parish register entries. To avoid the tax, some people did not register events.
1733	English replaced Latin in many registers. The exact date English was adopted by each parish varies considerably.
1737	Howell Harris and Daniel Rowlands introduced Calvinistic Methodism in Wales. In 1811 the Calvinistic Methodists separated from the Church of England and became a separate sect.
1752	The first day of the year changed from 25 March 25 (Lady’s Day) to 1 January.
1754	Lord Hardwicke’s Act required a separate register for marriages and outlawed marriages outside of the Church of England. Common law and nonconformist (except for Quaker and Jewish) marriages were outlawed.
1812	The George Rose Act required Church of England christening, marriage, and burial records to be kept in separate registers, starting 1 January 1813. Printed forms were used.
1837	Civil registration of births, marriages, and deaths began. Events were still recorded in church records. Bishop’s transcripts became less common, and they completely ceased by 1900.
1840	The first missionaries of The Church of Jesus Christ of Latter-day Saints began preaching in Wales at Overton, Flintshire.
1851	A religious census was taken which indicated that 75 per cent of the people were nonconformists.
1910	The government commissioned a study which determined that more than 25 percent of the people present at religious services regularly attended the Church of Wales.
1922	The Church of Wales became independent from the Church of England by an act of Parliament.
