Mary Cheney was born 1683 in Massachusetts to Joseph Cheney (1647-1704) and Hannah Thurston (1650-) and died 1705 Massachusetts of unspecified causes. She married Benjamin Cheney (1675-1718) 14 November 1706 in Charlestown, Middlesex County, Massachusetts.
Biography
It appears that Benjamin and his first wife, Mary Cheney, were first cousins, as his father Thomas and her father, Joseph were brothers, (Parents William and Margaret). It then seems, from the dates, that Mary died a few days after giving birth to their third and fourth children, twins May and Hannah. Benjamin remarries, taking 18 year old Mary Harbert as his wife a little more than a year later.
