I'm having issues with Lurene Purviance ... I think I listed her daughter instead of her. Reviewing this, her age doesn't match for the Lurene in the 1920 Census.
If you go to PeopleSmart.com and type in her name for Missoula, it comes up with TWO set of each name: for Lurene and for W. E. Purviance. I think they had two children and named them after themselves... just a thought.
