Information from the very helpful CADW:

The slab you are referring to in the Sacristy is weathered out. Our records on site says it is
"cut to represent two coffin lids with foliated crosses. The northern half has traces of a crosier and an inscription of leaded letters:
[HIC}JACET HENRICUS DE LANCAUT QU[ON]
DAM ABBAS DE VOTO
Lancaut is the name of a peninsula on the Gloucestershire side of the Wye below Tintern. The abbey de Voto was a daughter of Tintern, founded in Ireland by William the Marshal, Earl of Pembroke, in 1200.

The southern has similar lettering:
HIC JACET JOHANNES DE LYUNS
Who John de Lyuns (or perhaps 'Lyons') was, is not known. The stones are undated; but probably belong to the 13th century."

Indeed - I am very impressed with them.
