I've gone off on a tangent ...
I've just had a look at everyone living in Stephen Street in 1841. Granny Shepard and Uncle John Shepard are there (as is Ann Fox) so it seems like this is how these people knew each other. It's Matthew Ward who's living at Richmond Buildings, so perhaps the accomodation was better or cheaper there than Stephen St which is the reason that the Shepards and Nat eventually moved there. I thought that Nathaniel and mother Mary might be hiding in Stephen St somewhere but I couldn't see them. Maybe someone else might like to double check.

Then I got to wondering again about Matthew Ward and the fact that he can't be found in 1851. I know we found a couple of possible deaths. I quite like this one:
Mar 1847
Matthew Ward
St Pancras
vol 1
page 287
I can't see this on the London PR's on Ancestry. Does anyone know if there is a way to view this d/c without purchasing it?
Mongibello, is this something you are able to look up?

There is one burial on Ancestry for a Matthew Ward 23 Jan 1847 - he was living Marylebone age 75.

Is this the same Matthew Ward as the one from FreeBMD above? If so, I don't think he's our Matthew Ward. Age is way wrong too ..... Would a death in Marylebone be registered in St Pancras?
Our Mary Ward was buried 29 Oct 1847. She was living Richmond Buildings. Is this her on FreeBMD?:
Dec 1847
Mary Ward
St Pancras
vol 1 page 328
I'm just trying to tally up the right deaths/burials with the right registration districts and of course the right Matthew and Mary.
I'd really like to find Matthew Ward ...
