They are: Mrs. Ickes - Violet Sweethaven, Mrs. Wallce - Vesta Cummings, Mrs. Perkins - Doris Fleeson, Mrs. Morganthau - Jane Eads, Mrs. Hull - Ruth Jones, Mrs. Cummings - Beth Campbell, Mrs. Woodring - Dudley Hermon, Mrs. Farley - Bab Lincoln, Mrs. Swanson - Julia Bonwitt, Mrs. Rober - Mary Hornaday.
