William Blethyn

William Blethyn was a prebendary of York and a bishop of Llandaff. He died in 1591.

Blethyn was reputed to have been born at Shirenewton Hall, a large country house at Shirenewton in Monmouthshire, although his descendants were also said to have resided at Dinham, in a mansion on the site later occupied by Great Dinham Farm.

He was educated at Oxford, at either New Inn Hall or Broadgates Hall. He took orders, became archdeacon of Brecon in 1567 and also bishop of Llandaff in 1575, holding several livings at the same time in order to boost the scanty endowments of the see.

He died in October 1590, leaving three sons, and was buried in the church of Mathern.
