Drykid, I believe the buildings for sale are rebuilds, but in the original style. There are some buildings on the corner of Dean St which look pretty grotty and I believe may be original, but don't quote me on either of those opinions.
Deb, as usual I am unsure of districts, but maybe Matthew was no longer living at Richmond Buildings when he died? It could be him. I will think about buying this certificate too.
Something I thought that might be worth considering (and which I have really little or no knowledge about) is wills. I wonder if any of the family made a will? Mary? Granny Shepherd? This Matthew Ward who died in the Strand district?

Does anyone know how and where to check for wills?
