There are no very early Church registers belonging to the church and those in existence are in a poor state, badly written and often carelessly kept. This may well have been because the parish was a Royal Peculiar with no proper diocesan supervision.
The earliest registers date from: 1653 for Baptisms, 1654 for Marriages and 1653 for Deaths. The Churchwardens account books, giving each farm in the parish, with the owner and occupier, and the amount of the church rate to be collected from each, together with their expenditures are complete from 1674 to 1872 when the Churchwardens ceased to be overseers of the poor.
These registers and other documents not in actual use are now kept in Cornwall Record Office, County Hall, Truro https://www.cornwall.gov.uk/community-and-living/records-archives-and-cornish-studies/cornwall-record-office/
