Did Lew Parker and Rosemary De Camp guest star on any OTHER comedy series on the 1970's?

Rosemary De Camp appeared on 4 episodes of The Partridge Family between 1970 and 1973 as Shirley Partridge's mother, Amanda Renfrew.

I looked Rosemary's credits up and found that she also appeared on Love, American Style in 1973, and The Love Boat in 1978.
