 Here's a five page article which details multiple stories of people who have hair growing long all over them (see photo). There are multiple black and white photos of these people with exceedingly long hair and a few drawings as well. In a couple of the photos it appears that the same long hair trait was passed on to their children. One Russian guy named Adrian with the overly long hair problem had yellow eyes and greyish skin. Adrian had a son which also had the same problem and who later become "Jo-Jo the Dog Faced Boy". The description of the Adrian guy sure sounds like the beginnings of a werewolf myth though with this yellow eyes, greyish skin, covered in hair, and living on the forest. Or at the very least a perpetuation and reaffirmation of the existing werewolf myths.
