Related or not?

The more observant of you may have noticed that my main webpages have been updated (Big Brother).
The list of recent changes is rather bunched up on yesterday, mainly because that was when I checked off the people updated since the last publication - and of course found and fixed all (most of?) the typos etc.

Jemima PARKER appears because I've been fossicking around seeing whether or not any of the  FamilyFinder matches of descendants can shed any light on her and William CLINTON's ancestry - and seeing if there are any lines of enquiry left to pursue.
This time round I decided to see if anything could be found via the marriage witnesses, given I'd a question mark on the spelling of one of them.
The witnesses to their 1810 marriage at St Alphage were given as a James [H/K]UZELL  and Ann CAMPBELL, and after a few false starts on what the name was most likely to be, I found what looks a likely pair marrying at St Alphage in 1813, James HAZELL and Ann CAMPBELL.

Anyone know anything about the family?
Dragged off the street to be witnesses? Friends? Relations? Waiting around in the church for another event?

I'm still digging, but it looks like James might have been a leather cutter, and may still have been alive in 1842 but I've not yet positively identified him or any of the family (daughters Sarah Ann, 1814, Charlotte, 1815, James Henry 1820, all baptized St Giles, Cripplegate) in the 1841 census.
There's a possibility in Essex which piqued my interest given Jemima's background, another in Berkshire and another in Somerset, which latter I think can be discounted. Jury still out on the others.
