Parents of Torchwood operative Gwen Cooper. We first met them on the occasion of Gwen's marriage to long-suffering fiance Rhys. It was clear that they did not get on with his mother, Brenda. Both were shocked to see that Gwen was pregnant, as she had not informed them she was expecting a child. She was really carrying an alien Nostrovite, having only been impregnated through a bite the night before. Gwen told her parents all about her work with Torchwood after the ceremony - only for Jack to later Retcon the entire wedding party so they would not remember any of the strange events of the day.
Some time later, the surviving members of Torchwood found themselves under attack following the events of "Miracle Day", when people suddenly stopped dying. Going on the run, Gwen and Rhys left their baby Anwen with Geraint and Mary. By this point, Gwen had finally revealed the true nature of her work with Torchwood.
Geraint had suffered a couple of heart attacks prior to Miracle Day, but on suffering a third after it took place he fell into a coma. His condition meant that he was one of those who were to be cremated alive. Gwen arranged for him to be smuggled out of the hospital and he was hidden at home by Mary and Rhys. A Government official investigated and found him - and he was sent to one of the holding areas awaiting cremation. When the Miracle was overturned, Rhys was at Geraint's bedside and was able to allow him to speak to Mary by phone before he died.
