Bought from a small antique shop in Sussex in approx 1979. May have belonged to a religious order or person. St Nona is not in any Dictionary of saints but is also known as St Non or St Nonnita. Mother of St David of Wales. Possibly born in Dyfed and married to a local chieftain named Sant. Supposedly went to Cornwall and died in Brittany. Her relics were enshrined in Cornwall until the reformation. Nothing else known. Any further datails appreciated.
