Elli was a religious leader and theologian active in 6th-century Wales. While traditions regarding the saint's gender vary, historical accounts link this figure to the lineage of King Brychan. As the foster child of Saint Cadoc, Elli received an education at the Llancarfan settlement before eventually succeeding Cadoc as Abbot. The saint is closely associated with several locations across Carmarthenshire and Monmouthshire, most notably through the founding of a church near the River Lliedi.
Life and work
Born around 501, Elli was the son of Grimbul's queen. Following an education at Llancarfan, the saint rose to become the Abbot of the settlement. This religious leader established a church near the River Lliedi, a site that eventually grew into the settlement of Llanelli. Some historical interpretations suggest that the traditions surrounding Elli may actually represent two different individuals.
Veneration
The saint is recognized within both the Roman Catholic and Eastern Orthodox churches, with a feast day observed on January 23. Llanelli serves as a primary site of association, and the Church of Llanelieu may be dedicated to the saint. Various churches throughout Carmarthenshire and Monmouthshire also maintain connections to this religious figure.
