Although I do not have direct information about the parentage of Daniel Stanard, I am also researching the Stannard families that lived in New Marlborough and Sheffield, MA. I am descended from John Stannard who died about October 1773 at New Marlborough; his widow Hannah (Hanchett) Stannard married in July 1780 Jared Huxley. When John died, at least seven of his 11 known children were under the age of 18. As far as I can tell from my research, only two of the six sons of John and Hannah remained in Berkshire County after the Revolutionary War - John Jr. and Jeheil; the latter married Wealthy Sisson at Sheffield December 1824; this was probably at least his second marriage given that he was 58 years old at the time.
Please let me know if you want to share information.
