Three of Ephraim and Elizabeth Hartwell's children — Samuel, John and Isaac — were in the Lincoln minutemen that fought at Old North Bridge and on the battle road.

Paul Revere and William Dawes were detained by a British Army patrol nearby during the "Midnight Ride" to Concord of April 18.

Prescott emerged at the Hartwell Tavern, awakened Ephraim and informed him of the pending arrival of the British soldiers.

Despite her best efforts and those of Lexington physician Joseph Fiske, the soldier died of his wounds two or three days later, and he was buried near the farmhouse."
