The parish church (Church of Scotland) has registers dating from 1660. Old Parish Registers (before 1855) are held in the National Records of Scotland in Edinburgh, and copies on microfilm may be consulted in local libraries and in LDS Family History Centres around the world. Later parish registers (after 1855) are often held in the National Records of Scotland as are any records of non-conformist churches in the area (often unfilmed and unindexed, and only available there).
Graham and Emma Maxwell have transcribed and indexed the Chirnside Burials 1817-1854.
The Scottish Genealogy Society has published "Berwickshire Miscellany - Ayton & Chirnside" containing Ayton Communion Certificates 1829-1848, Ayton Communion Certificates received 1830-1839, Chirnside Male Heads of Families 1834-1837, and Chirnside Register of Interments 1817-1841.
The parish registers available worldwide on microfilm include some kirk session records:

- In part 730/2: accounts for 1704-1810

The presence of non-conformist churches in the parish is revealed by Rutherfurd's Southern Counties Register and Directory which lists the following in the year 1866:

There may have been other non-conformist churches at different times.
