Hi Andy,
I have checked out the House on Goose Hill on your website and assuming that your ascribed date of ca 1680 is correct then this is only 43 years "newer" than New England's oldest standing timber framed house - The Fairbanks House, Dedham Mass, ca 1637. To describe the House on Goose hill as a "fixer upper" is probably more than a little insensitive but I am very pleased to hear that you are now seeking to improve your knowledge and understanding of timber framing and timber framed buildings - presumably in relation to your interest in the "conservation" of old buildings.
I would strongly recommend that you purchase, read and absorb the contents of "The Framed Houses of Massachusetts Bay, 1625 - 1725" by Abbott Lowell Cummings (ISBN 0-674-31681-9).
Regards
Ken Hume
