How do I gain access to the 1921 or 1931 Census. I am trying to find where my Grandfather (Philip Arthur Adams) was born. The only reference I can find to him is his Marriage Certificate in 1908. Although my Grandmother (Martha Annie Leeman) appears in both the 1891 and 1901 Censuses I cannot find either of them in the 1911 census.

I know when they were married the lived at 49 Hopwood Street Sculcoates
in the County Borough of Kingston upon Hull, Yorks ER. 49 Hopwood Street is missing from the 1911 Census. They Later moved to Cambridge Street which is where I hope to find them in 1921 or 1931.

I am a British Citizen living in the USA and will be coming to England in one weeks time for a 3 week holiday and I wanted to look at the Censuses. What do I have to do?

All help will be gratefully accepted.
Joe.
