Very much post 1810. I had a quick look and non conformist records for Heytesbury seem to start in the 1880's. The records I'm interested in are from the first half of the 19th century.

Most early non-conformist records (where they survive) will already be available under RG4, 5 etc. The governement of the day collected most of the pre 1837 registers, so they could be used as proof of birth. Masses of people registered their children at Dr Williams Library in London, even if they had already been baptised elsewhere.

This collection is potentially very useful, as it's from the county record office. Thanks for letting us know, Kite!
