Hello Rick,
I would contact the vicar of the parish church and ask if it would be possible to see the original parish registers. The chances are that many of the gravestones will be quite weathered and virtually illegible or missing altogether. Furthermore, only the baptismal registers are available online. The marriage and death registers would go a long way to confirming the relationships.
Your family had such a long presence in the village I'm sure that the vicar would be interested in providing assistance.
You should also perhaps seek advice in the 'Common Room'.
