Frederick of Utrecht
Frederick I was Bishop of Utrecht between 815/816 and 834/838 AD, and is a saint of the Eastern Orthodox Church and Roman Catholic Church. His name is sometimes Latinized as Fridericus Cridiodunus.
Frederick was born around 780 in a noble family from Frisia. 16th-century folklore mistook him for a grandson of the Frisian King Radboud. According to Church records, he died on 18 July 838 but other sources give dates between 834 and 838. In any case it is certain that he was murdered.
At a young age he was taught at Utrecht by the clergy, including Bishop Ricfried. After completing his studies he was ordained priest and put in charge of converting the remaining heathens in the northern areas of the diocese, but also in areas outside of the diocese. It is known that he preached at Walcheren and together with St. Odulfus in Stavoren and its surroundings.
