Jeff Horton was the father of the late Lisa Horton and father in-law to Terry Duckworth and grandfather to Tommy Duckworth. Jeff and his wife Doreen didn't approve of their daughter going out with Terry, especially when he was arrested for GBH and received a custodial sentence. He was also unimpressed with Terry's parents, Jack and Vera Duckworth, and made no effort to be friendly to them when he and Doreen came to Weatherfield to meet them for the first time. Despite his feelings, Jeff agreed to pay for Lisa and Terry's church wedding, with Terry being given a day release from jail to marry Lisa. They witnessed Terry running off when he was un-handcuffed by his prison officer, and returned home to Blackpool when Lisa decided to stay in Weatherfield in case Terry got in touch.
