Being Excommunicated
Although Meidung refers to being disowned by the Amish, Bann is a far more serious punishment. You’ll be placed in the Bann and considered as an outsider if the transgression is serious enough to result in permanent ex-communication. You may be rejected for a longer length of time based on your “crime.” Even if it appears harsh, the goal is for the person to admit their mistake and apologize.

DNA Testing
Thanks to modern technology, almost everyone likes to get DNA testing to learn more about their ancestral and possibly locate long-lost relatives except for the Amish, who will not allow it. That is why it is so simple to marry your third cousin in their community. They believe that inbreeding is a result of God’s will.
