Ages of Marva and Diane
I know Rose was the oldest of the girls but I am confused about ages of Marva and Diane. After seeing the series all the way through since it aired, I am convinced that Marva was the second oldest due to her and Rose having classes together in episodes and that she was more mature than Diane (i.e. neatness issues in "Wilderness Blues". Can anyone help with this issue? Thanks!
