Who they were
Ceiddio (6th cent.), of family of Caw, Patron of Rhodwydd Geidio, Anglesey, and Ceidio, Carnarvon.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
Stanton's Menology of England and Wales (1887) lists him among the Welsh saints to whom churches are dedicated.
