Establishing a Baseline

Short and sweet today.  I posted all of the historical docs and maps and photos in "Reference Pages" (see links at left).  Essentially, this is what we "know".  Everything else we've got is:

• Basically immovable landmarks and clues: foundations, stonewalls, well heads, relational references to other documented properties and landmarks, etc.
• Info from the local Historical Society (Wiggin Memorial)
• Resources from the local Library (also a Wiggin Memorial)
• Anecdotal "Evidence" and Oral History from locals re: the last of the Wiggins to live in this house around the turn of the last century.
• Observations from driving around town looking at the (many) other period homes, their architecture, their size, their scale and those little plaques provided by the local Historical Society (hint!)

Based on all of the above and a couple of hours perusing "A Field Guide to American Houses", we are pretty sure the house was built after 1767 and before 1790, and most likely in the pre-Revolutionary period of that window.  It's certainly a side-gabled Georgian.  It now has paired interior chimneys, but it may originally have had one central chimney (with very cold outlying bedrooms).  The major sticking points (I think):

The space between the top of the second floor windows and the roof overhang puts it later in common applications.  But there are notable exceptions (Brice House in Annapolis and Williams House in Deerfield).  Also, there are a couple of 1717 and 1723 houses around here with a good 14" between windows and roof.

The front door is the (potentially original) solidly Georgian (1700-1780) front door paired with the more commonly Adam (1780-1820) leaded elliptical fanlight and sidelights (also potentially original) on the front door. But, leaded glass elements and fixtures were commonly wedding gifts and Richard was unmarried when he was deeded the land in 1767.  Maybe the fancier front door was a wedding present?

Still pondering.  As always, input welcome!
