Mary Dyer, English-American martyr (born 1611)

Mary Dyer was 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 due to their theological expansion of the Puritan concept of a church of individuals regenerated by the Holy Spirit to the idea of the indwelling of the Spirit or the "Light of Christ", which was deemed dangerous heresy. She is one of the four executed Quakers known as the Boston martyrs.
