Yes, sorry to say Bonnie has passed away. She died recently in 2007 while living in Vegas. She was cremated, and her remains are still with Vicky. You had mentioned Van as one of their sons, that is my father. His name is Joseph Vance Coble, but he does go by Van. Also, I am not sure if you had heard, but Mike died some time ago, and more recently Pat passed away in 2006. To answer your question, Bonnie's last name was still Mustain at her death. Although she was 'with' a man with the last name Voile which for a time she used his last name, she didn't have it legally changed.
