Thankyou Kite and Merry.
I tend to overlook events further west than the City as so few of my ancestors hail from there. Although Joshua and Frances were born in Laleham, west of London!
Joshua states that Mr Fox was of Kent Street. The Victorian London Streets A_Z names five Kent Streets: Bethnal Green, Shoreditch, Southwark, Newington and Plaistow. Of course they probably moved about - none of my ancestors stayed in one place for long - but I was favouring the four first areas due to the fact that the Settlement Exam is for Shoreditch Poor Union and that she died in Newington.
I will have a look at the Chelsea Foxes (that sounds like a Channel Five programme
) and see if I can find a connection.
