Jackson Smith
From Tardis Wiki, the free Doctor Who reference
Jackson Smith, the father of Mickey, had worked as a key-cutter at Clifton's Parade. Some time before 2002 he went to Spain and left his son alone. Mickey went to live with his grandmother, Rita-Anne.
The father of Ricky Smith, Mickey's counterpart, had done the same. (DW: Rise of the Cybermen)
