Maud's Line, by Margaret Verble
I checked this historical novel out of the library because I actually knew a woman who grew up in Oklahoma with Native American roots. She, like Maud Nail, was a spirited spitfire! And she too often found herself dependent on men, much to her chagrin.
Maud lives with two incompetent men...her father is an alcoholic wanderer with a temper, and her brother is a troubled dreamer. Maud essentially keeps their homestead going.
When a peddler stops by, Maud's life changes...not only her own circumstances, but also that of her father and brother. She is a free-spirited heroine of the midwest. I didn't always agree with her decisions, but I enjoyed reading about her adventures.
