Bolton, Massachusetts, marriage register, p. 70: "Nathaniel Oak, Jr. of Bolton | Susanna Hastings, of Bolton | .. | June 2, 1773." The same page lists two other Oak marriages at Bolton (Seth, 1757; Benah, 1767).

How it is shown: The legible rows of the register page (a clean crop; the full page is not otherwise held); no retouch, no search highlight.
Keep in mind: Confirmed for the date and place (an upgrade candidate over the earlier Probable); the groom is recorded as "Jr." and who the implied Nathaniel Oak, Sr. was is an open question, not resolved. The two other Oak marriages on the page are unconnected leads.
