Where was Great Grandad Thomas in 1841?

[Brenda in Cyprus]

Thomas Parker was born in Penge Surrey in 1833.I have him on the 1871 census living at 2 Holland Rd Croydon with his wife & children. Can anybody help me find where he was prior to this, particularly as a young child. U fortunately I don't know his parents names yet
Many thanks
Brenda
