St Berchert

Saint Berchert was an early mediaeval English monk, commemorated in several churches in Ireland. He probably came to Ireland as part of the wave of Northumbrian exiles led by Bishop Colman of Lindisfarne following the Synod of Whitby in 664 AD. His feast day is celebrated on 6 December.
A stone slab at Tullylease bears the inscription BERACHTUINE, suggesting Berchert's original Old English name was Berhtwine. Close by the former monastic site of Tullylease is St Berrihert's Well.
St Berrihert's Kyle in the townland of Ardane also appears to bear his name, though may refer to another individual of similar name.
