Marie Sing was born on 10th March, 1930, at Wellington, NSW.
She moved with her family to Blacktown at age 15. Marie mentions that her family were not happy about her marrying a man with a Chinese background at first, but eventually accepted it. Both Marie and her husband were very involved with Blacktown Bowling Club. When Marie first took up lawn bowls, she had to play at Riverstone because Blacktown club would not accept female players.
