[1] Today, located in Lincoln, it is in the care of the Minute Man National Historical Park.

A Hartwell Road runs to the north of Hanscom Field, but its relevance to the developments of the late 18th century is not known.

[3] Another historian, Joyce Malcolm, countered the theory put forth by Toogood, after consulting the deed of Hartwell Tavern: There has been a suggestion that this road may have continued north between the farms of Samuel Hartwell and his father Ephraim to the old Bedford Road.

There is no solid evidence for such a continuation and a survey of the Hartwell farms executed in 1779 shows no such road.

[4]The route taken by "Virginia Road" on today's maps continues northwest for around 0.18 miles (0.29 km) from Hartwell Tavern to around 350 feet (110 m) southeast of the Bloody Angle, where British regulars were ambushed by the local militia on their retreat from Concord to Boston on April 19, 1775.
