Cyngar of Llangefni

As a mature man, he became a follower of his nephew, St. Cybi Felyn, whom he accompanied to Edeligion in South Wales where they built churches in Llangybi-upon-Usk and Llanddyfrwyr-yn-Edeligion before King Glywys of Glywysing forced them to leave.

[1] They then went to the island of Aran Mor in Ireland where they spent 4 years building churches,[2] after which they moved to the Llŷn Peninsula at Cricieth.

They finally established an important monastery at Holyhead, Anglesey,[3] from where Cyngar founded the church at Llangefni.

Ynys Cyngar, once an offshore island but now a coastal headland is located at the mouth of the Afon Glaslyn near Borth y Gest (Grid Ref: SH 5535 3658), where the Church in Wales church is dedicated to St Cyngar.

He died on 7 November of an unknown year in the mid-6th century (probably 550 AD) and he was buried in Llangefni.
