They're not all FLDS. I'm an ex sister wife from there. The Ranch land was originally purchased by a sub group of AUB. A pretty sizable portion of the Stockton/Humansville plyg people are still AUB.

There's actually multiple subgroups there. This particular sect was originally started with property bought and owned by those affiliated with the AUB. Those from flds and others came in later.

I am an ex sister wife. I lived in a sub group of the AUB 40 miles north of Springfield. There's quite a few people from multiple flds groups living at and around the humansville/stockton ranch.
