Under the website - http://www.ccfne.ns.ca/~museum/english/archives/articles/http://www.ccfne.ns.ca/~museum/english/archives/articles/ - the second story of the late hitorisn and archivist Father Clarence D'Entremont (in translation) talks about your Benjamin, his son William, and grandson Reuben.
From the Yarmouth Vanguard, Tuesday, January 10, 1989: Reuben Abbott, a school teacher, son of Joseph Abbott, of Argyle Head, left us a sketch of the hardship that his grandfather, Benjamin Abbott, and others, had to suffer during the first winter they spent in Argyle, 1762-63, when, to feed their families, they had to kill the "French cows" that the Acadians, who lived here, had left in the fields when they were sent into exile.
Reuben Abbott, in his sketch, referring to Nickerson Hill, says that on it there is "an old French burying ground, and a little distance from there is the remains of a French chapel". All these are very well defined and located; in other words, we know exactly where they were. Reuben Abbott goes on to say that "there is a number of little clearings which is plain to be seen in different localities, and the remains of a dyke and some old apple trees." On these clearings were located the Acadian houses; their cellars are still there. Not long ago, the dyke was still visible under water on the west side of East River, crossing one of its branches; it disappeared when the bridge that spans this branch was rebuilt.
