Mary Perkins was daughter of John and Judith (née Gater) Perkins, baptized in 1615, at Warwickshire, England. Her family immigrated to America in 1631, sailing on the "Lyon" from Bristol. In 1636 she married Thomas Bradbury of Salisbury, Massachusetts, considered one of its most distinguished citizens, land agent for his great-uncle Ferdinando Gorges and son of Elizabeth Whitgift, whose uncle John Whitgift was Archbishop of Canterbury under Elizabeth and James I.
