John James Frost
John James Frost oedd y perthynas agosaf at y rhai y cafodd eu cerrig beddi eu difrodi. Cysylltodd Mrs Bishop ag ef yn fuan wedi'r digwyddiad. Nododd ei fod yn byw gyda'i fam yn Y Watton, ond nad oedd yno ar adeg y cyfrifiad ym mis Ebrill. Mae ei dystiolaeth yn ymddangos isod:
"John James Frost on his oath saith
I live at 31 the Watton Brecon and live with my Mother. From information I received I went up to the Priory Churchyard on the 17th instant and found that three memorial stones to the dead had been injured. One was down and had been broken in half, one which stood up had pices chipped off it, and one marble stone had been pulled up and thrown down. They were memorial stones to relations of mine and I laid on information against the prisoner to prevent further damage.
