I'm not sure if this thread would be best here or on the occupations board but here goes:
I have an ancestor who died in 1841 (unfortunately before the census

) who is described as a licensed victauller - I have his death cert and will and he was resident in West Green, Tottenham.
I have a problem in tracing him further back as although I have an approximate year of birth going on the age in his death cert I have no other references to his age and none on his birth place. His marriage says of this parish so he could have been born in that parish or just a great a chance that he could have born absolutely anywhere else! I can see one possible baptism in Westminster and another in St Paul's.
Being a licensee I assume that somewhere there must be some paperwork related to his application for a license - I assume somewhere at the LMA. I tried looking on their website but got rather lost in their catalogue

Has anyone got any ideas where I should start to look for an application to run a pub in Tottenham in the 1840s? There may be no clues in it to help me go further back but hopefully it might include something of interest.
In the 1820s and 30s from his children's baptisms and marriages I know he was an engraver and one baptism helpfully says at The Bank of England.

From their website I can see there are a few records in their archives regarding staff members in that period so there may be some clues there but when I shall get to London to look at them I don't know.

Or if anyone has any better ideas on how to trace him back let me know. Thanks
