Canna was a sixth-century nun and religious leader living in southern Wales. Often described as a mother of saints, she was the parent of Crallo and Elian. Historical accounts suggest she was the daughter of King Tewdwr Mawr, a ruler of Cornwall and Armorica. Alongside her husband Sadwrn, she traveled to Britain with Saint Cadfan to establish two different churches, located in Anglesey and Carmarthenshire. Her legacy remains tied to the religious landscape of Wales through these foundations and her descendants.
Life and origins
According to certain historical writings, Canna was related to the saint Illtud, being either his cousin or sister-in-law. This connection may have led her to establish a church at Llangan. Her marriage to Sadwrn, who was a relative, resulted in their joint mission to Britain. Together, they founded religious sites in both Anglesey and Carmarthenshire, contributing to the early Christian presence in the region.
Veneration and legacy
Her memory is preserved through two Welsh churches dedicated to her. At the church in Carmarthenshire, a holy well called Ffynnon Ganna was once a pilgrimage site due to its perceived healing powers. A stone known as Canna's Chair also exists near the churchyard. Additionally, her name is reflected in the Cardiff districts of Canton and Pontcanna. She is commemorated on 25 October.
