13. Mike Minor
In season four, a crop duster by the name of Steve Elliot shows up, played by Mike Minor. The show introduced him as the love interest of Billie Jo, even though he ends up marrying the youngest daughter Betty Jo. Typical. Anyway, Minor stayed on until the end of the show, then took work in other shows, CHiPs, All My Children, and L.A. Law. At age 75, like too many cast member from the show, Minor succumbed to cancer and died.
