That's what I thought the position was re The Bull. Why Jolene and Lilian tolerate Kenton's interference is beyond me, unless he has been employed as bar manager or similar. He behaves like a part-owner.
Poor Jamie.
For the benefit of our newer thread members, The Bull used to belong to Jack and Peggy Archer, parents of Lilian, Jennifer and Tony, uncle and aunt to David, Shula, Kenton and Elizabeth.
Jack died from alcoholism. Peggy carried on as owner but employed Sid Perks to run the pub. His first wife Polly died, leaving him as single parent to a daughter Lucy who now lives in New Zealand and for some reason didn't get left any share of The Bull. He married Kathy, who used to be very vocal but is now so worn out from running Grey Gables that she is never heard on air. 
They were eventually able to buy the pub from Peggy with the help of a wealthy local man, Guy Pemberton. He died shortly afterwards, left his share of The Bull to his widow Caroline (Shula's best friend) and she eventually sold it so she and her new husband Oliver Sterling could buy Grey Gables (which she was running). As far as I can recall, that was when Lilian became involved. She bought Caroline's share out of sentiment for the good old days when she was growing up there.
Sid and Kathy had a son Jamie, who as far as we knows still lives locally and is a tree surgeon, but suffers from the same vocal chord problem as his mum. He owns a share in The Bull but appears to have forgotten about it just like everybody else.
Sid and Kathy had a dramatic break up when she found out he was having an affair with Jolene. (There was a scene in the shower which many still remember with a shudder. 
) Kathy couldn't really claim the moral high ground as she had also had an affair earlier, which Sid had decided to forgive.
After the divorce, Sid bought Kathy out and continued to live in The Bull and run it with Jolene. He then died during a trip to New Zealand to see Lucy. Jolene inherited almost all of his share. She took up with Kenton about a year after Sid's death, and they eventually married. It's a sign of how intricate all the relationships in Ambridge are that Kenton had recently broken up with Kathy (yes, Sid's ex), having lived with her for ?a few years. Oddly, he never mentions her or Jamie now.
Jolene has a daughter, Fallon, from her previous marriage to Wayne, who used to be the chef at The Bull (is he still there? can't remember). Fallon is married to the police sergeant Harrison Burns. They live in Woodbine Cottage on the village green. Fallon runs the tearoom at Bridge Farm, with Emma as her trusted lieutenant. Fallon and Emma also run (or used to) a business upcycling furniture and so forth.
Have I missed anything?
