In 1921, Avis got a job as a barmaid at the Rovers Return. She gave birth to twins Lucy and Ian Buck two years later. The kids were often left alone while Avis worked and Larry drank. On one such occasion before their first birthday, a fire started at No.9 which Larry discovered in time to raise the alarm. Tommy Foyle managed to save Ian but in all the confusion, Lucy was forgotten.
In 1925, Larry was arguing with Ned over who won the 1921 Derby when Larry knocked Ned across a table, smashing his head on the floor and killing him instantly. The death was ruled as misadventure but Larry still felt responsible and decided to leave Weatherfield. Taking a job at a tailoring factory in Newcastle, the Bucks moved east, where they had two more children - Joseph and Alice. Larry lived until 1948 when he was killed in an industrial accident. Avis was still alive in 1997, and had celebrated her 100th birthday.
