'Ch. b. Canterbury ... Sarah5 Cleveland, b. Sep.3, 1744-5 [sic], m. C., Sep. 21, 1763, Peter Stanton, b. C. May 18, 1743, a s. Joseph and Abigail.'
This source seems to have confused Peter's maternal grandparents (Joseph and Abigail Staples, as per "Unplaced Stantons") with his parents, Thomas and Sarah (Staples) Stanton.
'Thomas Stanton ... married ... Sarah Staples ... daughter of Joseph and Abigail (------) Staples. ... Children: ... Peter, b. 18 May 1742 (1743 by Canterbury V. R.); bapt. 13 June 1742 (Brooklyn church); m. 12 Sept. 1763 (Canterbury V. R.), Sarah Cleveland, b. 3 Sept. 1744 or 5, dau. of David and Eunice (Backus) Cleveland. In 1790 he was probably in Worthington, Hampshire Co., Mass.'
