It's my understanding that Daniel Boone and Davy Crockett are related,
and I'm wondering what that relationship is?

It seems that their relationship stems from the fact that they were
both chased by the same wild bear in Kentucky. Ironically they both
escaped by climbing an apple tree planted by Johnny Appleseed who
obtained the seed from Eve, a onetime resident of the Garden of Eden
who along with Adam we are all related. And even though we are cousins
I must say that 2.00 is not enough money for a question of this
magnitude. How ever let that be the problem of my other cousin the
google researcher who is too busy to answer this, probably because of
being chased by a bear.

They were both played by Fess Parker on TV
