Some stories claim Bettelin was a Mercian nobleman married to an Irish princess. While the two were travelling through a forest, the princess went into labour. Bettelin went for help, and while he was gone the princess delivered the baby; the two were eaten by wolves. This traumatic event reputedly sent Bettelin to the hermitage, but it's reliability is questionable.
