Ben Wainwright (1897-1920) was the father of Sally Wainwright, husband of Kathy Nightingale, brother-in-law of Larry Nightingale, and the paternal grandfather of Malcolm Wainwright.
When Kathy was taken back in time, to Hull in 1920, by the Weeping Angels, she arrived next to Ben with no idea what just happened. Ben later married her and died in 1962. He might be related to Sally because she walked off with Larry Nightingale, Kathy's brother. (DW: Blink)
