Mary's mother died when she was about a month old, so she was raised by her mother's sister Amy (Bates) Pettingill. In later census she is listed in the household of her father, John Hammond and his second wife Elvira. Like her mother, Mary also died about a month after the birth of her second child. Her son Harold's grave marker and some records incorrectly list Harold's year of birth as 1886 instead of 1885.
