Mawgan and Meugan (also Meigant) (Latin: Mauganus) are names referring to either one or two Brythonic saints who flourished in the 5th or 6th century.
The parishes of St Mawgan and Mawgan-in-Meneage in Cornwall derive their names from Mauganus.
[1] There is also a Machan in West Lothian (Scotland), as shown by the place-name Ecclesmachan, but again this may be a distinct figure.
No hagiographical Life survives for Mawgan or Meugan, but figures bearing Latinised versions of either of these names appear in the Lives of Cadog and David.
88", in the National Library of Wales, records several Meugan festivals, including Manchan of Mohill.
