A new member of the Sharlot Hall Museum

I'm sending a letter to become a member of the Sharlot Hall Museum. I'm planning on visiting Prescott, AZ and the museum this summer. I have a few queries to make of them as well. Hopefully, I'll be making some of the queries before I go. For one, I need to determine how to locate the unmarked graves of William Henry Carothers and his wife Lucretia. I guess I better start working on that next.
