Tysilio

Tysilio is a Welsh saint, believed to have lived in the 6th century. He is traditionally associated with the founding of the church at Llandysilio, which bears his name, in Pembrokeshire, Wales. Details about his life are scarce and often drawn from later medieval texts, making precise historical reconstruction difficult. He is considered a patron saint of the parish of Llandysilio. While not one of the most widely known Welsh saints, his veneration is primarily localized to the area where his church is situated. His feast day is typically observed on January 11th. Some traditions suggest he was a bishop, though this is not definitively established by historical records. The lineage of Tysilio is sometimes traced back to figures of Welsh royalty, a common feature in the hagiographies of early British saints, serving to elevate their status and importance within the Christian community. The church at Llandysilio itself is a historical site, with archaeological evidence pointing to early Christian presence.
