The records of Freeman of the City of London are kept at the Corporation of London Record Office, Guildhall.
One could become a Freeman through 3* different
'Servitude' - after a completed apprenticeship with a City Guild (or Livery Company);
'Patrimony' - after becoming a member of a Guild and being the son of a Freeman of the City;
'Redemption' - one bought one's way in.
*This is ignoring the honorary Freedom awarded sometimes to distinguished people).
Freeman were entitled to call themselves 'Citizen'.
