Crallo

Saint Crallo is a Welsh saint of the undivided Church, the son of Saint Sadwrn Farchog and Saint Canna, daughter of Tewdwr Mawr of Armorica. His mother later married Alltu Redegog, so that Crallo was a half-⁠brother of Elian Ceimiad.

According to the Iolo manuscripts he came to the island with Garmon and became a saint in the community (Cor) of Illtyd, whose nephew he is called. He founded a church and a community at Llangrallo in Glamorgan, where he is said to be buried; the place is now called Coychurch. In the churchyard stands a circular stone cross, once inscribed, which is thought to mark his grave. Edward Lhuyd notes his holy well, Ffynnon Grallo, beside the church, and says that his festival, which occurs in no calendar, was kept on 8 August. A saying among the Sayings of the Wise bears his name.
