Foster was the only child born to Edna and Glenn Elwood on February 26, 1936. Foster spent his childhood and early adulthood in Herkimer, New York, before relocating to Atlanta. In 1959, Foster married his high school sweetheart Donna Mills. The two had four children and a loving home. Foster is preceded in death by his parents, his wife, Donna Mills, his son-in-law, Steve Coker and his longtime companion, Martina Lyons. He is survived by his children: Dawn Coker, David Elwood, Kathy Powell (Brad), and Lisa Holcomb (Randy). He is also survived by his grandchildren who knew him affectionately as "Poppie": Christine (Chris), Taylor (Will), Abby (Sydney), Nick (Victoria), Madison, Reese (Caleb), Jaxon, and a great-grandchild, Harper. Foster was a loving father, grandfather, and friend, and all will miss him.
