Disputed Origins

Mary Day was the daughter of Margaret Robinson, not Mary Robinson. See discussions in the biographies for Margaret and for Mary for the reasons for the confusion and why Benjamin Day's wife was Margaret Robinson, not Mary.


Mary Day, daughter of Benjamin Day and his wife Margaret (Robinson) Day was born in Attleboro, Bristol, Massachusetts on Attleboro, Bristol, Massachusetts, United States upon the 28th of December.[1]

Some say she was born in the year 1717,[2] but the sources for that statement need verification by reference to original records.

On 17 February 1738/9, James Jilson (or Jelson) and Mary Day, both of Attleboro, filed their intent to marry.[3]

Some say that Mary died in Killingly, Windham, Connecticut,[4] but that information is open to question and needs to be supported by reference to more reliable sources.
