I gave it a start - added sources that I could confirm, and a little spot at the beginning. Realistically, I don't like using even a word-for-word source as a part of the bio, but I'm hesitant to take it out as it flows nicely and does tell her story. I'd be more likely to push that part down into the sources, and then rewrite her story based on how it sounds. She has a story that needs investigation, as I'd like to know more about the Dakota Territory - why were they advertising for "teachers"? Was it to lure young women into the territory for potential cat house girls and potential wives? There's more to this story than is in this excerpt. And Otis? He's got some interesting facts, but I'd prefer to see the story revolve around her and her perspective.
What I see here is a young, idealistic woman who saw the need to go out to the edge of the world to help others and found herself the butt-end of what amounts to a joke - a lure to take advantage of girls like her - and she stood tall and refused to let them control her destiny. I do agree that her story deserves more - I'll think on it a bit, but hopefully someone is inspired to take a stab at it from here.
