Hi
Though a really large amount of standard records are online - parish registers, censuses, passenger lists, some military service records and wills in particular, the vast majority of records held in record offices are not online and in the case of an archives like The National Archives with over 100 miles of shelved records not even indexed, though millions of records have been so far. It costs into the millions to get these records online, digitalised and indexed and is mostly done by subscription websites, so they go for the more popular records that will give them a return for the investment they make.
You need to contact Redbridge archives. Link given.
