Peillian

Peillian was a Welsh holy woman of the sixth century, the daughter of Coel Godebog of the kingdom of Rheged in the Old North, and the sister of Saints Cywyllog and Gwenabwy.

After they had to flee from Rheged, King Maelgwn Gwynedd gave them land on Anglesey, on condition that they keep to religious work and not seek a homeland of their own. Peillian worked with her sisters in the same region. She founded a church at Llugwy. The source gives no feast day.
