I saw the documentary on Discovery Channel and in it they say they are Pentacostal. The dresses and long hair on the girls is the giveaway. They look like a very happy family.
Oh, good! The long dresses aren't always indicative of that, but I know pentacostal young children who dress modestly and have long dresses. They mostly homeschool. They're just a neat family, no matter what religion they are. Maryxxx
