Alongside the national census of 1851 the Government also conducted a census in England and Wales of churches and chapels, endowments, sittings, attendance at religious services on Sunday 30 March 1851 and average numbers during the preceding twelve months. Reports were collected from local ministers. Martin shares some of the returns from the Tavistock registration district.
