Jackson Moseley Smith was the father of Mickey Smith.
As his relationship with Odessa deteriorated, around 1989, when Mickey was five, feeling that she couldn't cope with life anymore, Odessa committed suicide. By this time, Jackson was working as an engineer and a part time singer. He was horrified to find himself a single dad and worked longer and longer hours and further further away from home until he found a job on the cruise ships moored alongside Tower Bridge. He was employed as the Second Engineer, but has aspirations to move up and sing on the ships. A two month contract was followed by a six month contract and then another, and Mickey never saw his father again. According to Rose Tyler, Jackson "just wandered off" (PROSE: Rose)
