Mary Reardon was sentenced to 7 years transportation at Dublin, Ireland, for an untraced crime. She arrived at Sydney in September 1793 aboard the Sugar Cane and was living with James Haynes by 1806. She was recorded as Haynes widow in 1825, as a seamstress in 1828, and was receiving a widow's pension of £10 in 1830.
She may have been the Mary Haines who died in 1840 whose age was given as 65.
