Inscription:
In Memory
of Mrs Abiel
Chauncey who
Dep^ed this Life
July ye 30th
1758 in ye
73rd year
of her Age.

On the day Abiel died she was 72 years old, and ∆tatis suś (i.e., ∆, "Aged," in the XX year of her Age) 73.

Abiel Adams, dau. of Rev. William Adams and Alice Bradford, b. Dec. 15, 1685 at Dedham, Mass. She d. July 30, 1758 at Mansfield, Conn. presumably while residing with the family of her dau. Desire (Metcalf) Warner.

Abiel was the maternal great granddau. of Gov. William Bradford of the 1620 Mayflower passage and Plymouth Colony. The name "Abiel" is masculine and Hebrew in origin, meaning "my father is the Lord." It was a name used in early New England, but rarely seen today. In genealogy many have adopted the spelling of "Abial" for a female, which is the spelling found in the record of the birth of her children at Falmouth, Mass. and at her death in the Manfield, Conn. vital records. However, "my father" does not denote a specific gender in the user of the name, and for consistency with the prepondence of the records in which she appears, including her gravestone, the spelling of "Abiel" is used in this bio.

By an intention to marry pub. Sept. 3, 1707 at Falmouth, Mass., Abiel m. 1) Rev. Joseph Fowler, s. of Dea. Jonathan Fowler and Hannah Kenrick, b. Apr. 11, 1682 at Dedham, Mass. No corresponding record of the marriage appears in the Dedham, Mass. vital records, but that an intention was pub. at Falmouth indicates her intended husband was already residing at Falmouth as pastor of the newly constituted Falmouth Congregational Church. He d. at Falmouth Dec. 24, 1723.

Rev. Joseph Metcalf and Abiel Adams had seven children recorded at Falmouth, who are outlined in their father's memorial. The Metcalf Genealogy claims they had eleven children, two not recorded in the published Falmouth vital records. This includes the purported youngest child of the family, a dau. named Azuba, supposedly b. Nov. 28, 1723 at Falmouth.

Following Rev. Metcalf's death, at an unknown place after 1723, Abiel m. 2) Rev. Isaac Chauncey. Many writer's claim they married at Dedham, Mass., which is unlikely. By the late 1720s most of Abiel's children were residing at Lebanon, Conn. where they would marry. According to Robert S. Wakefield (Desc. of William Bradford, NEHGS, 1991), Isaac was the son of Israel Chauncey and Mary Nichols, b. Oct. 5, 1670 at Stratford, Conn., was a 1693 graduate of Harvard, and d. May 2, 1745 at Hadley, Mass. Chauncey's first wife, Sarah Blackleach, d. at Hadley June 29, 1720.
