I feel compelled to point out that stories need not be old to qualify as folk tales. Though the popular notion that Santa's sleigh was drawn by flying reindeer dates back at least to "A Visit From St. Nicholas", published 1823, the story of "Rudolph the Red-Nosed Reindeer" was written by an employee at Montgomery Ward in 1939, at the request of his boss, for distribution as a Christmas season promotion. Ten years later, the poem was set to music by country singer Gene Autrey. The famous Rankin-Bass stop-motion animation special linked below dates to 1964, and has been imitated -- but never quite matched -- many times since.

Humans are so very odd about names. I spend a fair amount of time on subreddits like r/UnresolvedMysteries and r/gratefuldoe, where the denizens can be laser-focused on finding who the unknown dead are, and giving them back to their families. The latter sub was founded, in fact, after reddit managed to crowdsource a solution for the identity of the Grateful Doe, a young man dubbed thus because he perished in a car accident after attending a Greatful Dead concert. They've ID'd several Does since, many of whom have had their names and stories released to the public by their thankful families.
