From the web site of St. Ansgar Catholic Church of Hanover, Illinois:
"Deep in his heart, he carried the desire to give his life for his faith, to show his love through martyrdom. Contrary to his wish, Ansgar died peacefully in Bremen on February 3, 865, and was buried in the cathedral. After his death, Sweden again returned to paganism."But all was not for naught: eventually, a crater on the moon was named for him.
Ansgar is also the patron saint of people whose life story wouldn't make a compelling movie.
