Sunderland was a much larger town in the early days. Ancient Swampfield included all of present day Sunderland and parts of Montague and Leverett.  The map below shows Ancient Swampfield, and more!  North is at the left.  The Connecticut River is at the bottom. Swampfield is the rectangular shaped tract on the bottom (West side) of this map. This old town was nine miles from north to south and extended north into what is now the Town of Montague. The “L” shaped land that wraps around Swampfield here is a proposed addition to ancient Swampfield which never happened.  Modern Sunderland is about 1/4 of the land shown here. (see the key map below.)

Below is a tracing of this map which makes it a little easier to understand the original. North is at the top. (This is from Pressey’s History of Montague.)

The key map left shows the approximate modern town boundaries on the 1714 map.  The original map does not appear to have been very well surveyed. Swampfield has a rectangular appearance here, but the true shape was more of a parallelogram like modern Sunderland.

This section shows the area of modern Sunderland on the 1714 map. MOntague’s Sawmill River is clearly labelled on the top of the image, as are the “Hunting Hills”, and “Mt. Tobe” (Mt. Toby).
the double lines on the left side depict the village of Sunderland- “Town Street”.
