Benjamin Carpenter was (along with William Blake the poet and his wife Catherine and Dorothy Gott) one of the additional signatories to the Swedenborgian conference 1789 (not in the printed list of 7.12.1788) and like the Blakes and Gott he appeared in no other Swedenborgian records.

He was admitted to Daventry Academy 1768, married 24.6.1799 at Clapham, Surrey, Sophia Lewis widow, and died 23.11.1816 (unitarianhistory.org and familysearch.org). He was mentioned as schoolmaster at Stourbridge 1783 in Lant Carpenter DNB 1780-1840 son of his brother George. His will PCC 1817 dated 28.9.1815 mentioned his brothers John, George & Thomas, his sister Elizabeth, his wife Sophia, his daughter-in-law Ann Lewis, and his friends Joseph Hancox sr & jr of Kinver. According to Dissenting Academies Online he was "a zealous advocate of Arianism". He adopted his nephew Benjamin Carpenter (born 1796 son of Joseph 1754-1803), who became a Unitarian minister at Nottingham. Another Benjamin Carpenter, painter and chandler of Hammersmith was insured SunFire 1792, 1797, 1807, but it was not as common a name as one might suppose.
