Eloise,
A list of Beachy Amish-Mennonites in Tennessee is at this link:

We are in Buffalo Valley, TN, between Carthage and Cookeville TN. We visit the Vernon Amish community near Hestand KY, just across the line from Celina TN. That is the closest "pure Amish" place that we know of. They have leather working, horseshoeing, a vegetable market, and a clinic that people come to from all over the world to visit. At the clinic they use Iridology to diagnose your illness, then tell you what herbs would be the best to help you find healing, at no charge and only accepting donations. Whenever I am stumped about a medical condition for me, my family, or my friends, I go there and use their diagnoses, as they have never been wrong so far. Absolutely amazing. They have a herb hike in the spring to help you identify the herbs you need in the wild. They have a horse powered sawmill for cutting firewood, and a horse powered drill for drilling wells. No electricity at all.
We also visit the Muddy Pond community, just east of Monterey TN, probably 50 miles north of Morrison - they have 2 or even 3 types of plain churches, one I think one is Holdeman Mennonites. I used to talk to John Guenther, who ran the sorghum mill there. They have a large general store with herbs, vegetables, and other items much cheaper than elsewhere. The sorghum mill is steam powered and is a huge operation in the fall. They also have a buggy manufacturing facility, also steam powered, with a turbine that turns an overhead shaft that runs all of the machinery using belts that can be engaged to the shaft. Most of the buggy making equipment is something out of a museum. Just amazing.
In Cookeville, there is the "Malco Produce Market" on Willow St, run by young ladies in long dresses and head coverings. Not certain what affiliation. I think their farm is near Standing Stone State Park, north of Cookeville.
My friends down the street from me dress plain, long beard for the man, headcovering for the women, have known them almost 20 years, they left the Church of Christ to live for Christ, and found that plain living was the right way to go. They have many Amish and Mennonite friends, a lot of them from Lobelville TN.
Etheridge TN near Lawrenceburg is another place where the Amish live.
My great grandmother is from Pelham, TN, and other family from Hillsboro, TN, south of Manchester near Morrison and Viola, TN. It is a beautiful part of Tennessee in that area. There are literally "plain people" everywhere here. We are just "born" that way here.
For the Amish to be successful, they have to find excellent farm land in a place with few people. This part of Tennessee is perfect for a plain lifestyle. But being "plain" does not mean you are always affiliated with a traditional Anabaptist sect.
I hope you enjoyed your visit to Morrison.
John
