I couldn't find him in 1841/51 either. I've often initially thought that some of my ancestors might have been missed off a census, but other than one family which is definitely missing, I've eventually found them all, or have found an explanation eg fighting in the Boer War in 1901. I wonder if he may have been a regular in the military, possibly the navy, as he lived in Greenwich from 1861 onwards. This is where his marriage certificate might prove useful as it should give his occupation.
I've struggled over his occupation in 1861 - I managed the "labourer" bit without any problem! - it's the rest that caused me strife. I think it's an abbreviation for Royal Arsenal "Rl arnl", which employed many people in that part of London.

There are too many Edgley burials in Ramsey to make it possible to narrow down the field. Why do you think his parents were William and Ann? If it was, as you say, a guess then that's a surefire way to research someone else's ancestors!!!
I'm not sure if the lady who has the Ramsey transcript still follows this board, as her last message was in November 2006.
A couple of people on GenesReunited have David EDGLEY b 1812 in their trees, but I'm not a member so can't contact them. One of them might even be the lady with the Ramsey transcript, as her christian name's the same.
Hunts is not the easiest county to research as the LDS was not allowed to film many of the parish registers, and many of them haven't been transcribed either, so Huntingdon Records Office is the only place where the registers can be viewed. Fortunately for those of us who can't make it to Huntingdon they do run a reasonably priced research service.
Kind regards
