Tathana

Saint Tathana was a saint of south Wales of the 5th century. Very little is known of her life. She is believed to have been born around 465 and to have been a granddaughter of Meuric ap Tewdrig of Trebeferad.

She lived humbly, as a virgin and hermit, in a mud hut on the river Thaw, and was associated with the monastic school of Llantwit Major, where she was buried. One tradition says that the village of St Athan in the Vale of Glamorgan is named after her, but it is more probable that the name comes from the male Saint Tathan, to whom the parish church is dedicated. She is honored as a saint of the undivided Church, in the old Welsh calendars.
