Yes, I'm back on the magical research. According to RA Gilbert's Golden Dawn Companion, this was one of the meeting places of the Hermes Temple of the Stella Matutina. I'm guessing one of the members lived there, but I'm not sure who. I'd probably need to cross-check the census records with the membership rolls, and the latter are quite patchy, anyway.
