St Cenydd (Kenneth)had a hermitage somewhere off the Gower; it could have been on the island of Burry Holms where a 6C chapel has been excavated. He also had a church and holy well at Llangennith on the Gower; a recently found 9C stone could be his grave slab. He later went to Brittany.
Troparion
Renouncing the world you sought out a desert
on an island off the Gower where you could pray.
Deformed as a child you were reformed in the Spirit
and the fame of your name went far and wide.
Holy Kenneth pray for us.
