In reply to your query. Yes Both William (Will) or (Bill) Carter and Hattie are buried in Post Falls, as are the Butterfield parents. Not so very far from each other as it happens. As they are my grand parents I tend to visit the grave sites as time and situation allows. Lois I. Carter (Medley) is there as well. Bessie, my aunt, is buried, I believe in Clarkston Washington.

In re-reading your information it looks like the information for my aunt Bessie should be that for her mother. Both my aunts' birth date and my mothers' birth date appear to be correct.
