Jeff,
I was doing genealogical research on the Dacy family, and saw your posting on Ancestry.com. I am Don's (and your) cousin (my dad, Ralph Dacy, Sr. was your dad's uncle). Don (he was known as Donnie in those days) and Gail lived with us during my junior year at Raytown High School. Your mom is my old friend Ed's sister. Do you know where Gail lives now? She may know where he is. I maintain contact with several Dacy cousins, and I may be able to help you find him.
Ralph
