I recently had a flashback to my childhood and remembered hearing about Davy Crockett (with the song about him being king of the wild frontier). I never heard about Davy Crockett without a mention of Daniel Boone, but then I realized I had no idea if they were made up folk heros like Paul Bunyan (which reminded me of the John Jacob Jingleheimer Schmidt song) or if they were real people.
Turns out Crockett and Boone were real, along with Johnny Appleseed, who I always thought was a legend.
