The Cartwrights’ well-meaning, but irritating eastern cousin causes chaos on the Ponderosa.

Trivia: This was Nina Foch’s only appearance on Bonanza. In 1963, she appeared with Michael Landon as a guest panelist on the game show Stump the Stars. Foch was portrayed the first person to be murdered in the long-running series Columbo, in the pilot episode “Prescription: Murder”. For the last 40 years of her life, she taught at USC’s School of Cinematic Arts.
