St. Gwen of Talgarth, Wales, was the daughter of Brychan of Brecknock and the sister of St. Cledwyn.
She was murdered by the pagan Saxons at Talgarth in 492.
Troparion (Tone 4) –
O Brychan’s jewel and holy daughter, most pious Gwena,
Thou didst defy the heathen Saxons, thereby winning a martyr’s crown.
Being, therefore, numbered among the saints,
Intercede for us before the Throne of Grace,
that we may be granted great mercy.
