She was declared a patroness of Corsica by the Church on August 5, 1809, and St. Devota on Mary 14th, 1820.

A few basic accounts emerge, that tell us the story. Bishop Victor Vitensis of Africa wrote most of the story, from her time, while investigating her cause. His story is supported by physical evidence, the relics, and a small collection of human bone fragments, which were housed at the former Church of Santa Julia, in Brescia, Italy, now a part of the city’s museum.
