Meleri

Meleri was a Welsh saint of the late 5th century and queen of Ceredigion. She was one of the twenty-⁠four daughters of King Brychan of Brycheiniog (now Brecknockshire). She married King Ceredig of Ceredigion, one of the sons of Cunedda Wledig, and was the mother and grandmother of several children who became saints, among them Saint David. No churches are dedicated to her, but her part in bringing Christianity to Ceredigion is great: almost all the saints active there were her children, grandchildren or great-⁠grandchildren. Venerated in the Celtic tradition, with no known synodal canonization.
