Hello Gram,
The 1841 street index lists Minerva Place, Terrace and House, Old Kent Road as HO107 488-17 folios 32-34. Mason Street is listed as folios 10-21.
I've checked the whole area as best I could, but couldn't spot any Hoyle family. Many of the images on my CD's are out of focus, so they could be in the area, but just unreadable. Sorry not a very positive reply.
