I need to find proof of two things for this Ephraim. First, that he was born circa 1759, and second, that he resided with his father in Worcester County MA at the beginning of the Rev War, and later moved with his father to Shaftsbury VT and maybe lived with his uncle Colonel Ephraim Doolittle in Shoreham VT around 1781-83.
The source for his birthyear is the book "The Doolittle Family in America." The earlier volumes of this book place him in Colonel Ephraim's family but Volume VIII correctly gives his father as Samuel (1719-1792.) I need some proof, other than family history that he was born in 1759. The 1830 census lists his age as between 60 and 70.
From "The Doolittle Family in America" Part IV page 483 Compiled by William Frederick Doolittle, M.D., 1904: “Ephraim Doolittle b. 1759 Beekmans Manor, Dutchess NY." Of course there is no proof in Dutchess County, only that his father bought land there.
I thought I had the second part regarding his residence in either Worcester MA or Shoreham VT covered by the following two sources: Enlisted in War on Sep 28, 1777, Petersham, Worcester Co., MA, from Massachusetts Soldiers and Sailors of the Revolutionary War. Vol. 1-17. And when he moved with his father to Shaftsbury VT and was involved in the Alarm of 1780, cited in Rolls of the Soldiers in the Revolutionary War 1775 to 1783. Rutland, VT. It appears that the DAR requires proof not just of his service from a particular region but also of his residence there.
There were some land records that were post-1783 but so far none that would prove where he resided during the war.
