20 years sounds good, however my dad went back 25 and could not find George, I'm sorry I'm not as good as my dad was I should have checked the IGI, but I did go and look and found several for Mary Harding including one that states Mary Daw Harding, so young Mary b 1753 could be the same one this would have made her 17 years old when she married George, not out of the question. plus the parents. Good work Thank you
