A bunch of my husband's ancestors lived in Great Barrington, so I've read a lot about the town's history. Of particular interest is the extraordinary woman W.E.B. Du Bois claimed as his great-grandmother:
http://en.wikipedia.org/wiki/Elizabeth_Freeman_%28Mum_Bett%29Elizabeth Freeman (c.1742 - 1829), in early life known as "Bett" and later "Mum Bett", was among the first black slaves in United States history to be awarded her freedom in court based on the illegality of slavery. Her county court case was cited as a precedent in the Massachusetts Supreme Judicial Court case of Quock Walker which is considered to have abolished slavery in the state. . . .
Freeman was born into slavery at the farm of Pieter Hogeboom in Claverack, New York where she was given the name, Bett. In her early teens she was given to John Ashley of Sheffield, Massachusetts, the husband of Pieter's daughter, Hannah. . . . John Ashley was a Yale-educated lawyer, wealthy landowner, businessman and leader in the community. His house was the site of many political discussions and the probable location of the signing of the Sheffield Resolves which predated the Declaration of Independence. Thus Elizabeth was regularly exposed to sophisticated political and philosophical thinking and argument. When Massachusetts' new constitution was adopted in 1780 she would have heard it read in the public square. . . .
After this reading Freeman sought the counsel of Theodore Sedgwick, an abolitionist-minded lawyer, to help her sue for her freedom in court, telling him "I heard that paper read yesterday, that says, all men are created equal, and that every man has a right to freedom. I'm not a dumb critter; won't the law give me my freedom?" Sedgwick willingly accepted her case, as well as that of a man named Brom who was another of Ashley's slaves, and enlisted the aid of Tapping Reeve, the founder of America's first law school. The case of Brom and Bett vs. Ashley was heard in August 1781 before the County Court of Common Pleas in Great Barrington. Sedgwick and Reeve asserted that the constitutional provision that "all men are born free and equal" abolished slavery in the state. When the jury ruled in Freeman's favor she became the first African American woman to be set free under the Massachusetts constitution. . . .
After the ruling, John Ashley asked her to return to his house and work for wages. Instead, she changed her name to Elizabeth Freeman and went to work in Sedgwick's household. She worked for Sedgwick's family until 1808 as senior servant and governess to the Sedgwick children (including Catharine Sedgwick who became a well known author) who called her Mum Bett. From the time she gained her freedom, she became widely recognized and in demand for her skills as a healer, midwife and nurse.
