Hi Mr. Thayer,
My recommendation is that you contact the Massachusetts Historical Society to get answers to your questions at their website https://www.masshist.org/
Thank you for contacting History Hub.
Good Luck in your search.
Dear Mr. Thayer,
Thank you for posting your request on History Hub!
The Massachusetts Land Records website by the Secretary of the Commonwealth of Massachusetts provides information on locating land records for Massachusetts. It includes records for the Berkshire Middle District where Tyringham is located. For additional information, please contact Patricia M. Harris, Register for the Berkshire Middle District, at Patricia.Harris@sec.state.ma.us.
We hope this information is helpful. Best of luck with your research!
