I am computerizing the Hardcastle family tree for the New Zealand branch and on looking back am trying to check details of earlier ancestors. John Hardcastle we think is my husbands 3 x great grandfather. The death dates for him and Hannah are correct and they had a daughter Mary. The birth dates are are not that close to what we have.
