Breton people
During the migration of the Britons from Britain to Brittany (c. 5th – 6th century AD), specifically during the invasion led by St Samson, Bishop of Dol, it is believed the Channel Islands came to be settled by them. There are numerous references to the habitation of Jersey by Breton people. This likely brought Christianity to the island. Various saints such as the Celts Samson of Dol and Branwalator (Brelade) were active in the region. Tradition has it that Saint Helier from Tongeren in modern-day Belgium first brought Christianity to the island in the 6th century; part of the walls of the Fishermen's Chapel dates from this period and Charlemagne sent his emissary to the island (at that time called "Angia", also spelt "Agna") in 803. A chapel built around 911 now forms part of the nave of the Parish Church of St Clement.
