hi, I have a John Calvert and wife Mary in the Ripon area. John was born in Pateley Bridge abt 1808 which makes him just old enough. Mary was born abt 1813 in Darley. They had a son Stephen and a Daughter Dina(h) who both appear on the 1881 census at their parents residence "Old Bank", Soothill Yorks. The children (adults at the time of the census) were both born in Timble Great, do you have place of birth or siblings for "your" John? Contact me if this ties in for you. Cheers. Mike.
