Unfortunately, I couldn't find the GREAT Ted Knight's yearbook. He did however drop out to enlist in WWII. It was cool to find the other cast members and in the process. BTW, Lydia Cornell's WIKI page has her five years younger than she really is. Woops.
Nancy Dussault, who played the lovely mother Muriel Rush. Washington-Lee High School in Arlington, VA. Senior, class of 1953.
Deborah "Debbie" Van Valkenburgh who played the oldest sister Jackie Rush. Hunter-Tannersville School (K-12) in Hunter, NY. Senior, class of 1970. This school was crawling with Van Valkenburghs!
Lydia Cornell (Korniloff) who played youngest daughter Sara Rush. Scarsdale High School in Scarsdale, NY. Senior, class of 1971.
Last, but not least! Jim J. Bullock who played the dimwitted Munroe Ficus. Permian High School in Odessa, TX. First picture, Junior, 1973. Second and third pictures, Senior, class of 1974.
... Of course I would not forget you, Mr. Knight. RIP.
