John East Dix, silversmith, Lonfon, ENG

Does anyone on this board know of John East Dix, wife Isabella Hookham (marr, 1805, Finchely) children John, Isabella, Ann H., Katherine M., Robert H., Eliza A., Hougham and John East.
I beleive he was a silversmith (although some rercords just say "gentleman") in London area. He had grandson Edward A., born about 1847 in Russia.
Curious to find out if there were descendants.
