1841 Census Kensington -
I think the whole of the sub district of Kensington Town is lost in 1841. That's about 17,000 people. Rather more than just some pages missing.
The National Archives report that part of Earls Court is missing in 1841 (what survives is in HO107/690, in Brompton sub district, maybe just in ED 7)
Probably the missing will include much or all of Earls Court Road which may be what they are meaning by your Earls Street?
Marriage said father was a Labourer. In Piece 690, in Sloane Place, near to Chelsea I guess, there is actually a John Corcet (does say that), 45, Labourer. Who he is I don't know, but I suppose that there is just the remotest possibilty if he was really Corbet that he might be your man.
You need the registers of St Mary Abbots really.
