Hello Carole.
Sorry about the inaccuracies, the information i gleaned came from Familytree and Freecen which has the 1871 census for Whitchurch, Familyseach has trees listed for the Richards family.
I have the marriage cert for Thomas Williams and Mary Jane Richards 1880 and iut shows that Mary Jane father is Thomas Richards a labourer. I turned to Roots chat to get some clarity on the family, whilst i now have chapter and verse on the Williams side, i had nothing on Mary Jane Richards and have only just started to research her.
