who did betty white play on mama's family
List of Mama's Family characters Ellen Jackson (née Mary Ellen Harper), who made sporadic appearances in the sketch comedy, The Family, and its spin-off sitcom, Mama's Family, was played by Betty White.
Mama's Family To fill the void left by Mama's grandchildren, Allan Kayser was cast as Thelma's delinquent teenage grandson Mitchel "Bubba" Higgins. Bubba was the son of Ed and Eunice. Bubba was ordered to live with his grandmother after being released from juvenile hall and placed on probation. Also added to the cast was Beverly Archer, who played the new character of Iola Boylen, the family's wildly quirky and prissy neighbor and Mama's best friend. Her catchphrase was calling out "Knock, knock!" in place of ringing the doorbell.
