Mary Snow the daughter of Joseph Snow was borne the : 17th day of october : 1674.
Source:General Society of Mayflower Descendants. Mayflower Families through Five Generations, Vol. 6 (Stephen Hopkins), p. 18, suggests Mary "perhaps" married Person:Nathaniel Mayo (11). However, as the discussion on Nathaniel's page explains, it is far from clear that he married more than once, and it is known he married Mary Brown. It appears the only real reason for believing this is that Mary is not mentioned in her father's will of 1717, and Nathaniel's first wife, if he had two, would have died by 1703. However, that would still leave three children, and those don't seem to be in the father's will either (the will is printed Source:NEHGR, p. 47:188-9). So this seems doubtful.
