Geoff Noble

Geoffrey "Geoff" Noble was Donna Noble's father and Sylvia Noble's husband. He was walking his daughter down the aisle, during her wedding to Lance Bennett, when she unexpectedly disappeared in a burst of golden light. As baffled as anyone else, Geoff took charge of seeing to the injured in the wake of the Robot Santas' attack on the wedding reception, and was overjoyed when Donna returned safely home after her adventure with the Doctor.(DW: The Runaway Bride)

As Sylvia tells her daughter, in April 2008, that she has had a tough year "with your Dad", Geoff may have died between December 2007 and April 2008.

Behind the Scenes
Howard Attfield was due to reprise his role as Geoff Noble in Series 4, but he died in November 2007. His scenes were refilmed with Bernard Cribbins playing the character of Wilfred Mott, who had already been filmed for the Christmas special, Voyage of the Damned, and was subsequently retconned to be Donna's grandfather.
