The house in Jermyn Street is the home of Lord John Grey's mother, Benedicta, as well as the occasional home of John himself.


Upon her remarriage to Sir George Stanley, the house remained in Benedicta's possession (in practice if not in law).[1]


The house has a portico at the front and a large foyer. To the right of the foyer is a drawing room, to the left a library. Beyond the foyer is a hall leading to the kitchens and other servants rooms.[2]

Given the period and style, it's likely that the house is 4-5 stories, with bedrooms on the upper floors and servants' rooms toward the back of the house.
