cousins

(S03E07) How did the cousins become the cold, unfeeling mutants we've perceived them to be? It started with a dunk in the beer bucket. Uncle's lesson may have been about family, but what sunk in to the youthful psychopaths was how to kill someone in one minute. A minute would turn out to be their undoing ...

I couldn't quite place the name, but Byron played Patty Duke's mom on the mid-60s sitcom The Patty Duke Show ("They're couuuuuusins...identical cousins!"). She was also a semi-regular on The Many Loves Of Dobie Gillis before that, and was once married to Michael Ansara, who was also once married to Barbara Eden.

Byron died on February 3 in Mobile, AL, after getting an infection from hip replacement surgery.
