(Chipman's Harwinton, p. 24.)  He was among the first settlers of Harwinton, and resided there from 1733 to 1770.  Both he and his son Ebenezer were signers, 1751, of the petition to erect the new county of Litchfield.  He was a grantor of that part of the town called East Harwinton and, in 1759 and 1760, bought and sold land in Nine Partners, New York.  (Cutter's Genl. and Fam. History of Central New York, p. 695.)     In 1770 Ebenezer removed to Pittsford, Vermont, being one of the first settlers there and an Original Proprietor.  The first meeting of the proprietors was held at his house, 19 March 1771, and he was chosen Moderator.  (Caverly's History of Pittsford, p. 708.)  He held town offices in both Harwinton and Pittsford.

4.  A.M. Caverly.  1872.  History of the Town of Pittsford, Vt.  Tuttle & Co., Printers, Rutland, VT:

p. 32	Ebenezer Hopkins was born in Waterbury, Conn. in 1699, married in 1728, and settled in Hartford.  He became one of the original proprietors of Harwinton in the same State, and removed there in 1733.  He had three sons, James, Nehemiah, and Elias, the two former born in Hartford, the latter, and a daughter, Tabitha, born in Harwinton.
p. 36	This year begin the earliest existing records of the Proprietors' meetings.  The record of the first meeting is as follows: 'March 19, 1771.  Warned by Gideon Warren Proprietors' Clerk.  A Proprietors' Meeting Now Held at the House of Ebenezer Hopkins [footnote: This house was built by James Hopkins and his father, but as it was designed for the fahter's use it is here called the house of Ebenezer Hopkins], Firstly Voted and Chose Ebenezer Hopkins Proprietors' Moderator to be Moderator for Sd Meeting.  Then Voted and Chose Benjamin Cooley Proprietors Clerk.  Then Voted to lay out the first Division of Lots and Number the Same.  Then Voted and Chose Isick Rood First Committy Man.  Then Voted and Chose James Hopkins 2 Committy Man.  Then Voted and Chose Moses Olmstead Committy Man.  Then Voted to ad Ten acres to every Loot in the first Division for Highways.  Then Voted that every Man should
p. 37	have his Hundred acres where he has Don his Work. [footnote: Up to this time no division of lots had been made among the Proprietors, but those who had settled here, did so on rights which they had purchased, andthey had made their pitches without regard to any particular system; hence this vote that 'every man should have his hundred acres where he has done his work.']  Then voted that all the Lots be the same size.  Then Voted to give the Committy three shillings a Day.  Then Voted to have the same Committy lay out the Hiways.'
p. 708	[capsule biographies] HOPKINS, EBENEZER SEN., of Harwinton, Conn., m. and had sons, James, Nehemiah, and Elias, and daughter Tabitha, who m. Dr. Abiathar Millard.  Ebenezer Hopkins, Sen., d. at Shaftsbury, while returning from a visit to West Stockbridge, Mass., about the year 1784.
The Ebenezer whom Caverly calls "Senior" is our Ebenezer "Junior."  The Moses OLMSTED mentioned by Caverly is possibly related to Mary (BUTLER) HOPKINS, whose mother was Elizabeth OLMSTED/OLMSTEAD (Elizabeth had a nephew named Moses).  The 1785 plat map contained in Caverly shows the HOPKINSes and OLMSTEADs between them owned about half the land immediately surrounding the village of Pittsford.
