Both 1841 and 1851 UK Census records show him as 35 and 45 years old respectively at 33 Tabernacle Row as a spectacle maker. He had entered a maker’s mark at Goldsmiths Hall from that address in 1837 as a small worker.
The death in 1870 of a Charles Davenport born around 1807 but without a last address was recorded in the Holborn registry and may be relevant.
