Nettie identifies as a man name "Melvin". The Mennonite do not allow members to identify as anything other than their biological sex and gender. In real life, Nettie would have been excommunicated. There are over one hundred different Anabaptist (Amish, Brethren, Hutterite, Mennonite) church groups, counting more than 6,000 congregations, all holding to slightly different traditions and their own interpretations of the Bible. The movie never identified the Anabaptist group of the colony.
