Jasper Jones’s father and Jack Lionel’s son, David Jones was a champion football player as a young man. He fell in love with Rosie, a beautiful Aborigine woman, but though he married Rosie and had a child with her, his father refused to acknowledge her for racial reasons. David and his father then had a falling out. When, later, Jack eventually befriended Rosie, and then accidentally caused her death, David stopped speaking to Jack, and never told Jasper that Jack was his grandfather. In the second half of his life, David fell into alcoholism and grief, and took poor care of Jasper.
