Mercy Lewis (ca. 1674 or 1675 – ?) was born in Falmouth, Maine. On September 30, 1689 an Indian attack killed both of her parents; as a result the 14-year-old Mercy was placed as a servant in the household of the Reverend George Burroughs. By 1691 she was a servant in Thomas Putnam's household. She played a crucial role during the accusations of the Salem witch trials in 1692, when 20 people were executed for witchcraft, including her former master George Burroughs.
After the trials, Mercy moved to Boston to live with her aunt. There she bore an illegitimate son. By 1701 she had married a Mr. Allen in Boston, Massachusetts.
