Rouse and/or Lee Homestead

Unknown subjects. My gmpa, William Flint, married Alice Rouse Lee in the 60s. When I was in Jr High, Gma Alice allowed me to use some of her old negatives in photography class. Her name was Rouse and they homesteaded in Charlo. Her brother(?), Charlie Rouse, wrote a book named, "Montana Bullwhacker". Her first husband was a Mr Lee and they had two sons. One was an MD and the other was a mill worker. This is one of her negatives that I printed up in school. I would love to find her family again.
