I'm so pleased you revived this thread Deb!!!!

I am also amazed that you found mention of Nat as a bookseller in 1851! That is wonderful. I love the way you think outside of the square - I would never have thought to look up Nat in directories as we thought he was always employed by others. Great stuff!
You description of the location of Percy Passage threw me for a minute. I think it was the mention of Fitzroy Square which is up near the Marylebone Road. (I searched for that rather than Rathbone Street on google maps

).
Found it in the end though.
Surprisingly close to Stephen Street.

If there are several of us who want to revisit this, what do you all think about starting another thread? (rather than tagging it onto the end of this one?) I'm not sure what more there is to find, but new records are coming online all the time ... got to keep hoping.
