Dr. Quinn, Medicine Woman/dr. quinns sister marjorie
did the lady who played dr quinns sister Marjorie on the show also play as one of hanks saloon girls to in some episodes, because I recall seeing her playing a saloon girl on the show
Yes (Alley Mills) did in play a saloon girl the episode "Happy Birthday" (season 1 episode 11) & was uncredited. From "Where the Heart Is" (season 2 episode 6) on she was Marjorie.
She's not the only person to play 2 parts in the series. Jason Leland Adams was General Custer in the first 3 seasons the Preston Lodge III for the rest of the series.
