It is also said that Revolutionary War soldiers such as Deacon Thomas Clark, Captain John Trull, and General Joseph Varnum, as well as others from this New England hamlet, traveled past the Pow-Wow Oak on their way to defend Lexington and Concord on Patriots Day, April 19, 1775.
In order that the tree might stand, O'Heir donated for one cent to the City of Lowell, 9,463 square feet of his land on Clark Road.
In May 1931, the Molly Varnum Chapter of the Massachusetts Daughters of the American Revolution (DAR) erected a sign next to the tree to commemorate the ancient oak, the Wamesit Indians, and the local militia who passed by it while traveling through that Lowell neighborhood (then still part of the town of Tewksbury) during the Revolutionary War.
On May 21, 2013, during a very strong wind storm, a large upper branch (not the lower horizontal "arm" that pointed west) of the Pow-Wow Oak collapsed onto nearby Clark Road.
