The Whitakers are known as "America's most inbred family," as documented by filmmaker Mark Laita. He was traveling through West Virginia for his YouTube series Soft White Underbelly when he encountered the family. He described his first meeting with them as "out of control" and "the craziest thing he'd ever seen."
Some members of the family are not able to speak, but they are able to communicate with each other - by pointing and grunting.
The Whitakers live in a community called Odd, West Virginia. It's known for being infamously tight-knit, with a population of around 779 people.
The surviving Whitaker family tree includes siblings Betty, Lorraine, and Ray, as well as cousin Timmy. Their parents were first cousins. Their grandparents had twin boys. Those twin boys each had a child - a boy and a girl. The boy and girl married each other, and it's believed they had 16 children.
