Connecticut, U.S., Town Birth Records, pre-1870 (Barbour Collection)

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier index.
The page confirms the name William Seymour as the husband of Mehetabel in New Hartford, with several children listed under "William & Mehetable". It gives no birth or death dates for William himself, so it supports the name but not the 1728–1782 life span. It is therefore consistent with the claim and does not fully establish it.
Matches: The page is from New Hartford Vital Records (Barbour Collection) and lists the SEYMOUR family, matching the cited source; William Seymour appears as the husband of Mehetabel ("Mehetabel, m. William SEYMOUR, Dec. 27, 1753", Vol. 1 p. 28); Children are listed as "[d. or s. William & Mehetable]", including Ester b. 1762, Noah b. 1759 and Jesse b. 1763, so a William Seymour was active in New Hartford in the 1750s–1770s
Limits: The page shows the name William Seymour only in references to his marriage and children. There is no entry for his own birth or death, so the 1728–1782 dates are not confirmed; The index does not say that this William is the person born in 1728, though the marriage in 1753 and children from 1756 are plausible for that birth year; The citation volume is given as 28, while the page's marriage entry points to Vol. 1 p. 28. This is probably a mismatch in the citation detail; This is a printed transcription of town records, not the original record; The spelling Seymour is confirmed, but the page does not say whether the name had variants
