1851 census has John and Mary with children William, John and Frank.
1861 census they have Betsy Smith married daughter with them
1871 is confusing, John is down as grandfather, with Jane as wife and William as son. But I think it must mean the household is Jane (wife of John's son William) and their William and Jane's son William (1864) who is John's grandson. William snr possibly away at sea on census night.
I can't see a Richard anywhere apart from with another John and Mary in St Austell
