That “White” clan is from Boone Co....but the family name is all over...it can be common in certain counties...but the one’s who have stayed generation after generation — they are Hollar People - and they won’t be leaving anytime soon...too illiterate to read a map and legally drive - let alone have enough money to buy gas once they cross state lines...
I saw that doc about the White clan. Interestingly, one White family male voluntarily pulled up stakes, left W.Virginia, and settled in Rochester, Minn. to escape his outlaw clan. I wonder how he’s doing?
