Well I'm working "blind" here , but you need to link this candidates age / year of birth to what you know about the Reginald you are trying to find.

If you have a close match, then you can try to track down Birth Certs etc to confirm by weight of evidence the hunch - or disprove it .

If there is a chance of a fit let me know and I'll try to lead you to the next step
