Asa Eggleson, Sr. (also spelled Eggleston, Eagleston, Eglestone, and other variants) was born in about 1735 in Stonington, New London County, Connecticut, the son of Isaac and Anna (Isaac) Eggleson. 

The Eggleson family owned a large tract of land that was right on the state line between Connecticut and Rhode Island and on the county line between Windham County., Connecticut, and New London County, Connecticut. Records for the Eggleson family can be found in Hopkinton, Rhode Island, Voluntown, Connecticut, and Stonington, Connecticut.

Asa Eggleson, Sr., has been reported by many sources to have married Joanna [suname unknown]. This is true; however, the oldest and presumably most reliable sources fail to mention that Joanna was Asa's third wife. The author's research of deed records of Stonington, Connecticut, Voluntown, Connecticut, and Hopkinton, Rhode Island, found proof that Asa Eggleson, Sr.'s wife as of 1773, was named Martha. A preponderance of evidence indicates that she was Martha (Button) Eggleson.

The Eggleston-Button Connection
"Most genealogists (since Frank Egleston Robbins), who have inquired into the history of the Eggleston family of Stonington and Voluntown, Connecticut, have accepted Robbins' conclusion that the parents of Asa Eggleston Jr. (1763-1840) were Asa Eggleston Sr. and Joanna ______. New research by this author indicates that, although Asa Jr.'s father was Asa Sr., the mother of Asa Jr. was named Martha and was probably Martha Button, born 30 January 1738 in Voluntown, Connecticut, the daughter of Matthias Button and Mary (Brown) Button..." 

What was the fate of Martha (Button) Eggleston? The records of Hopkinton state that "Asa Eaglestone and Sarah Lake, both of Hopkinton, were lawfully joined together in marriage on 31 December 1775." This implies that Martha died before the above marriage.

Hopkinton, Rhode Island Deeds Vol. 3, p. 572:
"...Asa Eagleton and Sarai Eagleton (wife to the said Asa) of Pittsfield in the County of Pittsfield and State of Massachusetts Bay..." sold for 45 pounds to "...Daniel Carpenter of Hopkinton in the County of Washington and State of Rhode Island and Providence Plantation yeoman..." 50 acres Jan. 19, 1786.
Asa Eagleton
Sarah Eagolston

This demonstrates Sarah was still living in 1786.

But what about Joanna? On 2 May 1796, Asa Sr. and three business partners purchased a large tract of land in Washington County, New York. That county's Deed Books contain several deeds in which Asa Eggleston and his three partners sold off their land holdings. In every case, Asa's wife is listed as Joanna.

During the American Revolutionary War, Asa Eggleson, Sr., showed his Patriotism by providing a substitute for military service. This was proven by the 1832 petition for a pension of his son, Asa, Jr., which stated: "The same year [1778], my Father Asa Eggleson was drafted [and] I went [as] a substitute for him in Capt. Burdick's Compy Col. Dyer's Regt. -Rhode Island Troops..."

The following was not submitted to the SAR with the author's supplemental application but should have been. In the Narragansett Historical Register (page 138), an article was printed called "The Patriots of Hopkinton, R. I., 1776", contributed by the Hon. Edwin R. Allen, Town Clerk of Hopkinton:

"HOPKINTON, 19 September, A. D. 1776

"I, the Subscriber, do solemnly and sincerely declare that I believe, The War, Resistance, and Opposition in which the United American Colonies are Engaged, against the Fleets and Armies of Great Britain, is: on the part of the said Colonies, Just: and necessary; and that I will not directly or indirectly afford assistance of any sort or kind whatever to the said Fleets and Armies during the continuance of the present war, but that I will heartily assist in the defense of the United Colonies."
 
162 men signed this Oath of Allegiance, and among them was "Asa Eaglestone [Sr.]."

Signing the Oath of Allegiance reenforces Asa Sr. as providing Patriotic Service to his county.

Asa Eggleson, Sr., was married first to Mary Buttons, then married a second time to Sarah Lake on 31 December 1775. She was living as late as 1786. Asa Sr. married a third time to Joanna [surname unknown] before 1796. Joanna was born in about 1746.

Asa Eggleson, Sr., and Martha (Button) Eggleson had four known children:

1. Asa Eggleson, Jr. was born on 19 February 1763 and married Content Hadsell.
2. Elipha was born on 15 March 1766 and married William Hadsell.
3. Lydia was born after 1765), and married Samuel Rogers.
4. John A. was born on 12 August 1775 and married 1) Martha Hadsell and 2) Arilla (Stuart) Beecher.

Asa Eggleson, Sr. and Sarah (Lake) Eggleson had two known children:

5. Jabez Eggleson was born about 1776-1777 and married Keturah [surname unknown].
6. Wilkinson was born about 1779-80 and married Betsey Caswell.

The Patriot died before 8 January 1816 in Greenwich, Washington County, New York. His intestate estate was administered in Washington County, New York. Joanna died on 7 April 1832 in Antwerp, Jefferson County, New York.
