I don't have a specific date for Hannah's birth, but I can offer this much from George Chandler's book "The Chandler Family: The Descendants of William and Annis Chandler Who Settled In Roxbury, Mass., 1637" [published 1883 ; Press of Charles Hamilton, Worcester, Mass.] Hannah was the 3rd of 8 children -- between John and William as you stated. John's birthdate is given as "14 March 1655". William's says "28 May O.S. 1659" ["O.S.", meaning "Old Style" calendar -- I think I have a book that explains that further, if you need it.] All of this preceding info is from page 11. On page 27 there is more info regarding her husband, Daniel (parentage, etc.); their children are listed on this page as well. Hannah's death is given as 20 Nov 1730 in Andover. Perhaps her death record [if there is one that early!] would tell her age, and bring you closer to her birth date .... just a thought.
