He entered a mark in 1808 at Goldsmith’s Hall in partnership with Frederick Comtesse as gold workers at 34 King Street, Soho.
He married Henrietta Huguemin at St George, Bloomsbury in 1809; they were both from that parish.
Two of their children were christened at St Anne, Soho in 1810 and 1812. His wife is recorded as Harriett.
At some unrecorded date Comtesse and Humbert notified Goldsmith’s Hall they had moved to 21 Hyde Street, Bloomsbury.
He entered his own mark in 1814 from 21 Hyde Street as a case maker and was recorded there on the christening at St George’s in 1815 of another of his children.
Another mark was entered in 1826 from Hyde Street as a case maker in partnership with Philibert Mathey.
He was assessed to Land Tax on property in Oxford Street until 1831, the last reference traced in the UK for him or his family.
