Folcwin
Saint Folcwin was a Frankish abbot, cleric and Bishop of Thérouanne. He was a contemporary of Notker of Liege.
He is venerated in the Roman Catholic Church and Eastern Orthodox Church on 14 December.
The first part of the Latin cartulary of St Bertin's is credited to St Folquin. A review of his life was written during the next century by his grand nephew Folcuin, abbot of Lobbes, on request of Walter, abbot of Saint-Bertin.
