During the show Little House on the Prairie, an uncredited actress appeared on 17 episodes of the series beginning with A Promise to Keep in season eight, through to include two of the final three two hour TV movies that finished the series in 1984.
The actress who portrayed Rose Wilder was never credited in the show’s credits, even in Bless All the Dear Children where the story line revolves around Rose being kidnapped.
We now know that Rose Wilder was played by twins Jennifer and Michelle Steffin. They both left acting shortly after Little House on the Prairie.
