John James "Johnny" Connor is husband to Jenny Connor and ex-husband to the late Louisa Connor with whom he had two children, Aidan and Kate Connor, Johnny is also the father of Carla Connor, following an extra-marital affair with Sharon Donovan, and the grandfather of Aidan's daughter Susie Barlow.
In August 2015, Aidan stole £100,000 from him and used the money to buy a share in Carla's factory, Underworld. Johnny tracked his son down during the following month and demanded his money back as he was penniless since his ex-girlfriend cleared him out.
In December, Johnny was sent a visiting order from Carla's brother, Rob Donovan from Highfield Prison. Johnny told Nick Tilsley about the letter but was unsure about telling Carla. However, she ended up noticing the letter and asked Johnny what it was about. Johnny told Carla that Rob had been in contact, and she urged Johnny to go and find out what he wanted. Johnny duly visited Rob, who told him he was Carla's dad. Rob knew this as his mother Sharon once told him that she slept with Johnny, and that Carla was born nine months later. Rob blackmailed Johnny, saying that he would give him a week to pay £10,000, or he would send out a visiting order to Carla. Johnny avoided the blackmail by telling Carla himself, after gaining certainty through a DNA test on a tissue she had discarded. His legitimate children were both angry with him when they found out, and Aidan virtually disowned him.
In May 2016, Johnny and his employee Jenny Bradley went to visit Blackpool so Jenny could properly lay her long deceased father Alan to rest. At the same time Tim Metcalfe and Kevin Webster were taking Jack Webster for a visit to the resort. While the trio were eating in the Seashore Snack Bar, Jack ran away. He was spotted by Jenny running past her towards an oncoming tram. Jenny sprinted after the boy and snatched him before he could be run over. Johnny rushed to see if Jenny was okay; her only injury was a twisted ankle.
Later that month Johnny discovered that Tracy Barlow knew about Carla's one-night stand with Robert Preston and warned her not to ruin Carla's wedding. On the big day itself, Johnny locked Tracy in a cupboard in the factory, hoping to stall her long enough so Carla could marry Nick.
In September 2017, Johnny and Jenny got married at Rita Tanner's hospital bedside when she was diagnosed with a brain tumour. Starting life as newlyweds didn't get off to a great start when they found the factory empty of furniture and even without the roof. They were further horrified when they worked out that Aidan's fiancée Eva Price had organised the factory and the bank accounts to be cleared out as an act of revenge for Aidan's affair with Maria Connor. When Johnny realised that Eva was responsible, he ultimately disowned Aidan.
- As stated by Michelle Connor in Episode 8804 (28th December 2015), Johnny is the second cousin of her father Barry Connor.
