Children of Jonathan Kidder and Mary Lamber: Ann, b. 24 Apr 1767, m. --- Sawyer of Reading.
↑ Hazen doesn't explain the basis for his asserted marriage, but says the father d. 1805. There doesn't seem to be a probate file in Middlesex for him, but at that time of his death, Anna/Nancy would have been married to Porter Sawyer, and probate files often give the married name without indicating the name of the husband. So this seems a good fit. She is the only real candidate that matches name and is a suitable age.
