The majority of the Mennonite population comprises so-called Russian Mennonites of German descent who settled in the Russian Empire during the 18th and 19th centuries. Most Russian Mennonites live in Mennonite settlements like Spanish Lookout, Shipyard, Little Belize, and Blue Creek. These Mennonites speak Plautdietsch (a Low German dialect) in everyday life, but use mostly Standard German for reading (the Bible) and writing. The Plautdietsch-speaking Mennonites came mostly from Mexico in the years after 1958 and they are trilingual with proficiency in Spanish. There are also some mainly Pennsylvania German-speaking Old Order Mennonites who came from the United States and Canada in the late 1960s. They live primarily in Upper Barton Creek and associated settlements. These Mennonites attracted people from different Anabaptist backgrounds who formed a new community. They look quite similar to Old Order Amish, but are different from them.
