Joyce Moon was born on 15th March, 1921, at Beelbangera, near Griffith in NSW.
Her father worked on Burrinjuck Dam before buying a poultry farm at Schofields, when Joyce was aged 2. Joyce married at age 22 and moved to Riverstone with her husband. The couple had a child and then later moved to Blacktown. After a number of years living in the heart of Blacktown, the family moved to Westmead, to be closer to Joyce's husband's place of work.
