I just stumbled across your post. I was glad to see our family legend corroborated. My grandmother was Rose Pelikan. Family legend is that Mildred fell in love with someone on the train while she and her sister Rose/Rosa were coming out from Nebraska. Mildred never reached Chicago, hopping off the train with her love somewhere before that. The story continues that Mildred and Rosa didn't speak to each other for the rest of their life. Don't know about that part: my father Paul Pelikan told it this way.
