Elisha was baptized 4 Jun 1637 at the First Church in Boston, MA.

Elisha was a freeman in 1666 in Connecticut.

Elisha signed the Pawcatuck Articles, in 1658, and was a deputy to the General Court in 1669.

"The action of the General Court of Connecticut in pushing its claims eastward to the Pawcatuck River, was by no means acquiesced in by Massachusetts, and the seriously controverted question of jurisdiction was referred to the Commissioners of the United Colonies for decision.

Meanwhile, or until the matter could be amicably decided, the planters were advised 'to carry themselves and order their affaires peaceably, and by common agreement.' Acting on this advise, the original settlers and a few others who had joined them, met together on the 30th of June, 1658, and organized a local government with what may be termed a constitution, entitled 'The Asotiation of Poquatuck people,' which was signed by eleven persons, viz.: William Chesebrough, and his three sons, Samuel, Nathaniel and Elisha; Thomas Stanton and his son Thomas; Walter Palmer and his two sons, Elihu and Moses; Georg Denison, and Thomas Shaw.

This compact is in the handwriting of William Chesebrough and pledged the signers 'to maintain and deffend the peace of the place and to aid and asist one another according to law and rules of righteousnes, till such other provition be made ffor us as may atain our end above written.' After affixing their names to the document, the signers chose Capt George Denison and William Chesebrough to be 'comytioners' to carry out the provisions of the contract.

Three months later the Commissioners of the United Colonies decided that the territory in dispute belonged to Massachusetts, and the General Court of that Colony named it Southertown and annexed it to the county of Suffolk. Southertown remained a township of Massachusetts until the issue of the Charter of Connecticut by King Charles, II, dated April 25, 1662, which fixed the eastern boundary of Connecticut at Pawcatuck River, this territory which for three and a half years had been subject to the control of Massachusetts, reverted back to the sister Colony. Through this period William Chesebrough held the office of Selectman."
