Our venerable and God-fearing Father Kingsmark (also Cynfarch, Cynmarch, Kynemark) was a monk, Scottish chieftain, and disciple of St. Dubricius of Caerleon in the 5th century. He later lived in Wales, where he grew to such renown for his holiness, that soon after his death he was glorified by the Welsh faithful. St. Kingsmark is said to have been married to a granddaughter of St. Brychan of Brecknock.
- Seeing that many were brought to Christ by the radiant example of thy virtuous life
- And thy missionary labours, O holy Cynfarch,
- Pray that we too may follow thee
- In the service of our Saviour, that our souls may be saved.
