Deb, Your query was so long ago I'm wondering if you have found the answers to your search for Mary Tibbets(Tebbets)Chamberlain's parents.Their names were Samuel and Dorothy(Tuttle)If you are still looking I can give you some more information. Actually the Tibbets(Tebbetts)family is from Dover,NH at that time,Dover Neck to be more specific. Wm. moved the family to Rochester later. Anna ,18 Jul 1733 ,in Rochester,NH was sister to my ggggg grandfather Samuel, 3 Nov 1735, in Rochester,NH. The Chamberlain family is quite well researched and so are the Tibbetts and Tuttles. Best wishes if your are still "out there".
