Saint Mechell was the 6th century founder and first abbot of the clas (a type of early Welsh/Celtic monastery) of Llanfechell, on Anglesey in north-west Wales. St Mechell's day is celebrated on 15 November. It is claimed that he is buried in Llanfechell. He was said to have been a Breton by birth. From the 14th century, he was identified with Saint Machudd, a Welshman and supposed Bishop of Caerwent who has been similarly confused with Saint Malo. Malo and Mechell both have 15 November as their feast day,
