Julia is Julia Lennon and John Dykin's eldest daughter. From the age of two the family lived on the Springwood Estate in Blomfield Road. When John restored contact with his mother he began to visit the family regularly. Whenever John stayed, which was often, Julia would share her double bed with Jackie to free Jackie's room for John.

Julia was 10 when she first saw John perform. His mother and his younger half-sister, Jackie, all came to watch the Quarry Men play at a street party in Rosebury Street on 22 June 1957.

The next year when Julia was 11, her mother was killed by a car, but the truth was hidden from the girls for several weeks. Their Aunt Mater looked after them first at her home in Scotland before they came to live permanently with their Aunt Harrie, supported by their father.

In 1965, when she was 18, Julia met Allen Baird. They married in 1968 and after the birth of their first child settled in Liverpool, then in Cheshire. Julia became a teacher. Allen and Julia went on to have three children together. Now their eldest son is a Systems Analyst, their daughter is in business marketing and their youngest son is studying music in London.

When John Lennon first moved to America Julia and he lost touch, but in 1974 a phone call out of the blue re-established contact and from then on John telephoned on a regular basis. He would often want to talk about their mother and the rest of his Liverpool family. He asked Julia to send him family pictures, especially photographs of their mother.
