Info on parents of Rachel Miller and the wife of Elnathan II

Trying to track down ancestors of Rachel Miller, b. 16 Jul 1766, m. Woolsey Baldwin (son of Elnathan II, b. 1724) b. 17 Sep 1756, d. 1 May 1832. Rachel and Woolsey had daughter, Betsy Stevens Baldwin, b. 9 Feb 1792, married Michael Johnston, b. 30 Jan 1789. Their son, Baldwin Johnston killed in Civil War, 1864, Raleigh, NC.
Also, how can an Elnathan Baldwin, son of Elnathan and Kaziah, marry a Kazia? Too coincidental. Is there no one with more information on Elnathan II and his spouse?
