Collen
Collen was a 7th-century monk who gave his name to Llangollen (from the Welsh llan meaning "enclosure" and 'gollen' being a mutation of "Collen"). 

Collen is said to have arrived in Llangollen by coracle and founded a church beside the river there. As there are no other churches in Wales dedicated to St Collen, it is possible that this St Collen may also have connections in both Colan, Cornwall, where Colan Church is dedicated to him, and Langolen, Brittany. There are legendary Lives connecting him with Wales, Rome and Glastonbury; but nothing is known for certain about him, though from the dedication of a church to him in Brittany it may be conjectured that he resided for some time in that country.
