Sadwrn
Saint Sadwrn (in Latin Saturninus or Saturnus) was a hermit. His feast day is 29 November.
History
St Sadwrn was the brother of Illtud (The Galilean) and is buried at All Saints' Church, Brixworth near Northampton. He seems to have held considerable sway in the politics of central Wales, which would have included contemporary north Carmarthenshire, and possibly like his brother, who followed St. Germanus, held a temporary military command.
There are strong Breton connections with the region which may explain their origins - a far more realistic explanation than the one usually offered regarding Sadwrn's (Giles) Armenian or Georgian roots.
There are references to Illtud being the cousin of Athrwys ap Meurig of Morgannwg although there is no known connection with Sadwrn. Caio, the centre of the early church in Wales, may have had a connection with Sadwrn but this is difficult to verify. Sadwrn and Meurig are deemed by some scholars to be St. Giles and St. George.
