Kathryn, Michael (My Dad), and their son Michael lived in California, most likely Newhall or somewhere in that region and/or Arizona.
The exact dates of the crash or burials are unknown. My father is a War Vet and had a very bad break down when this all occurred. You can understand it is hard for him to talk about or to get "dates" and specifics from him.
My Dad was also married to a woman Connie Lynn Sears. This is an entirely different woman from which he was divorced. She is the mother of my half sisters but little information is known of her either. She passed in 2010.
