Maches

Saint Maches was, in the 6th century, a princess and saint of Cornwall and Devon, according to some sources, the sister of Saint Cadoc. She was the daughter of Saint Gwynllyw and his wife Gwladys. She lived as a hermit and was murdered by thieves at Merthyr Maches (Llanfaches, in the kingdom of Gwent). She was buried in the monastery of Caerwent, now the parish church of Saint Stephen at Caerwent, by Saint Tathan, to whom the bandits had confessed the crime.

No other details of her life survive in the sources at hand. She is honored as a saint of the undivided Church, in the Welsh tradition.
