Richard Boone's publicity claimed he was a direct descendant of Dan'l's. Don't know about Pat.

Theme song went

Dan'l Boone was a man,
Yes a biiiiig man!
With an eye like an eagle and as tall as a mighty oak tree!
From the coonskin cap on the top of ol' Dan
To the sole of his rawhide sho-oe,
He was the rippin'est, roarin'st, fightin'est man
The Fron-tier ev-er knewwwwww!

Dan'l Boone was a man,
Yes a biiiiig man!
And he fought for America to make all Americans freeeee!
What a BOON,
What a DO-er,
What a DREAM-come-a-TRU-er was he!
What a BOON,
What a DO-er,
What a dream-come-a-TRU-er was heeeee!!!!!!


That's how I remember it anyway. The song was better than the show.
Fess Parker, not John Wayne, IS Davy Crockett.

Contrasting their depictions would be a nice term-paper topic....
