Don't know if this will help you but this comes from the Waldo family genealogy 1647-1900:
The will of Matthias Button of Preston, dated July 2, 1759, probated Aug. 7, 1759, names "wife Hannah" and "two grandson of my beloved son Zebulon Button, deceased."The will of Hannah Button, widow, of Preston, dated Jan. 18, 1772, probated Feb. 10, 1772, names--"grandsons Matthias and Zebulon Button." (Source: Norwich Probate Records, vols. i, p. 432; iv., p. 382.)april 14, 1779, a small piece of land in Preston was conveyed by "Sybill" Waldo of Stonington, Matthias Button of Preston and Zebulon Button of Stonington.This deed was witnessed by Susanna Waldo, probably sister of Cornelius, and evidently then unmarried (Source: Preston Deeds, vol. x, p. 34). Zebulon, son of Matthias (Peter) and Hannah Williams Button, born Mar. 20, 1721, at Preston; (Source: Preston Records) married May 27, 1742, at Preston, (Source: Stonington Records) "Sibbel Walbridge of Preston," Who was undoubtedly the "Civill," daughter of William and Abigail Larance Wallbridge, b. 17 June 1720 at Norwich, CT (Source: Norwich Records).But two children are recorded as born to them; viz., Matthias and Zebulon, who were named in their grandparents' wills.There is no evidence of there having been a daughter Sibyl, and it is probable that, in spite of the difference in their ages, the second wife of Cornelius Waldo was the widow of Zebulon Button.
As early as Mar 31, 1764, Cornelius Waldo "of Canterbury" purchased of Hezekiah Woodward of Stonington, a tract of land adjoining that of Zebulon Button's heairs, in Stonington, on the borders of Preston. (Source: Sontington Deeds, vol. viii., p. 27).In 1766, Sibbel Button bought a tract of land of which the bounds were not precisely defined.April 20, 1774, survey and agreement to fix these bounds was made as follows:
"Stonington, Apr 20, 1774Then at the Desire of Mr Cornelius Waldo and hsi now wife Sibbel who was the late Sibel Button on the one part and Mr. zadock Killam and his now Wife H annah on the other Part, with the Assistance of chain Men I surveyed a Certain tract of land Scituate in Stonington aforesaid; Containing Thirty three acres & fifty three rods, Thirty two acres & an half of which land was Conveyed to ye said Sybbel by Deed Executed the twenty fifth day of August A. D. 1766 Signed by sd Zadock & his sd wife Hannah as a part of their lands." etc.(NOTE: I typed this as it was spelled).
Cornelius Waldo died intestate, and at a court of Probate held in Stonington, apr 15, 1804, "This Court Hath Granted letters of Administration unto John Kimball on the Estate of Cornelius Waldow late of Stonington Deceased."The estate was inventoried at $242.31, all personal, and Sept. 24, 1805, distribution was made in equal parts, "To Irena Ames the wife of David Ames of Fairlee in the County of Orange and State of Vermont, a sister and Heir to sd decd" and "To Susanna Wait a sister and heir to the decd," (Source: Stonington Probate Records, vol. vii, pp. 219, 403)Sibil being evidently dead and no children, if any had been born, of which there is no record surviving.
