Hi
I've used Sourcer to put the Freecen site census for 1851 and 1861 onto the profile, looking at the household tables shows George age 36 and Joanna with sons including William age 6 in 1851, in 1861 George age 46, sons William age 16, and James age 9, head of household is George snr and his wife Grace. All males other than James are smiths.
Census dates/ages aren't always accurate, but both census looked at together show a family group.
