From 1558 until 1837 the parish registers were the official record of all christenings, marriages, and burials in the parish. These registers survive and have been printed (Register of the Parish of Addington, transcribed by the Rev. R. Ussher, Bucks. Parish Register Society, vol. XX, Aylesbury, 1916). Users of this volume should be aware that numerals in the original are often very difficult to read and numerals particularly may have been incorrectly transcribed. You may also want to consult the Bishop's Transcripts: these are contemporary copies of the register entries and often contain details now missing from the registers. Microfilms of the registers and the transcripts are held by County Archives and Local Studies Library for Buckinghamshire. Registers since 1837 continue to record christenings, marriages, and burials, and (apart from those still in use) have been deposited with the County Archives and Local Studies Library for Buckinghamshire.
Additional information is sometimes engraved on gravestones, although the earliest Addington gravestone dates to the 1680s, and even after that date many people were buried without a gravestone. The Addington inscriptions have been copied out, and the graves have been given index numbers. The rows are lettered A to R west to east, and the columns are numbered 1 to 60 north to south. These inscriptions are available on this web site.
