Don Van Vliet aka Captain Beefheart is now connected to the tree. His only rival for sheer rock and roll weirdness was Frank Zappa, his lifelong friend and mortal enemy.
Vliet was descended on his mother's side from famous Kentucky horsebreeder Dr. Elisha Warfield and was cousins with Wallis Warfield, King Ed's consort.
On his father's side he was cousins with cowboy actor Slim Pickens (Lindley-664, also connected).
