Hi and a warm welcome to Rootschat
As he was born before Civil Registration began in 1837, there will be no record of his birth. You will be reliant on Parish Registers to see if he was baptised (you may be lucky and find that gives a date of birth too). Not all PR's are online. He may never have been christened, or not been chr as a tiny baby. He may not have been chr in Redbourn itself.
So it may take a bit of working on - starting with Redbourn and then working through nearby parishes.
Do you know if he had any siblings who may lead you to his parents?
