I believe Sarah's uncle, Samuel Seaver, married Sarah Cutter, daughter of Nathaniel Cutter and Submit Whitcomb. My wife descends from Samuel Seaver and Sarah Cutter as follows: Samuel Seaver & Sarah Cutter had son Asa (dob 1799). Asa Seaver (1799-1868) m. Abigail Lewis (family moved to Parishville, NY) & had Sarah Lavina (dob 1838) Sarah Lavina Seaver (1838-1898) m. David J. Armstrong. I have a picture of David and Sarah, along with other siblings. I also have copies of David's obituary. Their son was Judson (dob 1867). Judson Robert Armstrong m. Carrie Mae Walker (a descendant of the Walker line tracing to Samuel in the 1640's). Their daughter was Doris Emeline Armstrong (dob 1901) who m. Thomas Ford in 1923.
I am interested in obtaining copies of the birth certificates or any other record of Asa Seaver or Sarah Lavina Seaver. If anyone can help, I would appreciate hearing from you.
