Besides the episode of "Perry Mason"from second season 1958-1959 -1959 's called "The Case of the Romantic Rogue",(a somewhat mean-spirited episode in which she played murder defendant Helen Harvey (the character was nice)whom Mason got off ,her character was REALLY innocent),and her OTHER series she did after "Happy Days"ended,called Brooklyn Bridge,what OTHER shows did you see Marion Ross in?

I liked when Ms. Ross was in Community Service (a tv movie) and when she played Drew Carey's mom on The Drew Carey Show.

Marion played Jeff's teacher on an episode of 'The Donna Reed Show'. And of course, we can't forget her performance as Dr. Porter on 'The Brady Bunch'.
