an English and colonial American Puritan turned Quaker who was hanged in Boston, Massachusetts Bay Colony, for repeatedly defying a Puritan law banning Quakers from the colony. She is one of the four executed Quakers known as the Boston martyrs. Before leaving Boston, Mary had given birth to a severely deformed infant that was stillborn. Because of the theological implications of such a birth, the baby was buried secretly. When the Massachusetts authorities learned of this birth, the ordeal became public, and in the minds of the colony's ministers and magistrates, the monstrous birth was clearly a result of Mary's "monstrous" religious opinions.
