There are no maps. In rural areas the houses did not have house numbers (still the case today) and the enumerators made up their own private numbering system to ensure every home had been visited. Their records have not survived. (Worth mentioning that most areas had different enumerators in the 2 censuses so the numbers often vary. House 3 in 1901 is not necessarily the same building as House 3 in 1911).
If your ancestors are listed in the Valuation Revision records then it may be possible to locate their property using the maps in Griffiths Valuation.
