The christening of Elizabeth, the daughter of Jacob and Betty More, was registered at St George, Bloomsbury in 1777.
He is listed in the 1795 London Poll Book, along with Robert More, as jewellers at 20 New Street, Covent Garden. He had entered a mark alone as a small worker in that year from that address. It is noticeable that the previously mentioned trade card and the advertisement do not specifically show the name Jacob but there may have been a partnership.
The Will of Jacob More, jeweller and silversmith late of Grove Street in the Parish of St Martin in the Fields, was proved for probate on 24th December 1801 (National Archives reference PROB 11/1367/259).
