There are two Hampshire Lansleys of the right sort of age living in Westminster, but I can't find Everett.
I can give you the rest of the household if you can't find it.
Presumably you have the other census entries such as 1841.
(The marriage entry is correct. The family have moved North by 1861. The Everett b 1850 will be a relation as he is from the same village (Kimpton) as the elder Everett).
