I realise you may have looked here already.The 1911 Census has this:In an address search for Raby Hall:
the result was RABY MERE Raby Wirral Cheshire
For the full transcript of everyone in the household the price is 10 credits which cost between 83p and £1.16
For the original document of the census of the household the price is 30 credits which costs from £2.50 to £3.48
But I think you may have to pay an initial charge of £6.95 for 60 credits.
Its a while since I used it and can't remember what my first payment was. 1911 Census address search
The LDS Family Search has the 1881 Census for free
but you need a name to search, which you might get from the 1911 census if you do that, and work backwards. Family Search 1881 Census
