Mary Garibaldi was the daughter of Michael Garibaldi and Lise Hampton.[2]
She was very fond of tennis which she played for her school team. She practiced with Dr. Stephen Franklin whenever he visited. She also seemed to be very close to Doctor Franklin whom she called Uncle Stephen. She later won first place in her first tournament. Like her father it seemed she had the potential to drive people crazy at times.
In 2281 Mary won first place in the inter-school tennis tournament while her father was away for Babylon 5's decommissioning ceremony.
