Much to Archie's dismay, Edith has always regarded the union of her cousin Amelia and wealthy Russell DeKuyper as the "perfect marriage." Thus it is no small shock to Edith when, while visiting the Bunkers, Amelia blithely announces that she and Russell are splitting up. Elizabeth Wilson and George S. Irving are cast as Amelia and Russell, roles originated by Rae Allen and Richard Dysart in the 1972 episode "Edith Gets a Mink." Written by Lou Derman and Bill Davenport, "Amelia's Divorce" first aired on January 25, 1975.
