I believe I am descended from John McLaughlin b. 1765 in New Boston, New Hampshire and d. 1805 or possibly 1814 in Sachetts Harbor New York. Wife Bethiah Wilkens. I would be related through their son Liberty Hiram b. 1803 in New Hampshire. How would I obtain documentation on my Rev. War Ancestor not being near a DAR Library of any kind???? Thank you for any help.
