I have just found I can do an address search on Ancestry for the 1911 census. I was looking for the person living at 55 Ward Street, Cleethorpes where a MACKRILL death had been recordes in 1909. I was hoping for a SMITH but no luck it was a HEMMINGWAY family. Go to the census summary books search page and enter the address in the Keyword box. This brings up the results page and your address should be the first entry. Take note of the resident and go back to the census search page and fill in boxes, last name eg "HEMMINGWAY" lived in eg "Cleethorpes, Lincolnshire, England", and the Keyword box eg "55 Ward Street" and you will have the residents.
