I can’t really read that, I’m afraid, but Bedfordshire Notes and Queries reckons that it says:
Close to the foundations of these walls lie | the remains of I Elizabeth Hyde | Wife of the Reverend William Hyde | Rector of this Parish | and daughter of the Right Reverend | Father in God, Thomas Watson, D.D. | Lord Bishop of St. David's | Who departed this life August 12th 1718. I Dum vixit | Inter Virgines formosa | In religione fidelissima | Uxorum praestantissima.
There was a dispute over Elizabeth’s will.
