As a relatively young lawyer, Sedgwick and Tapping Reeve pleaded the case of Brom and Bett vs. Ashley (1781), an early "freedom suit", in county court for the slaves Elizabeth Freeman (known as Bett) and Brom. Bett was a black slave who had escaped from her master, Colonel John Ashley of Sheffield, Massachusetts, because of cruel treatment by his wife. Brom joined her in suing for freedom from the Ashleys. The attorneys challenged their enslavement under the new state constitution of 1780, which held that "all men are born free and equal." The jury agreed and ruled that Bett and Brom were free. The decision was upheld on appeal by the state Supreme Court.
Bett marked her freedom by taking the name of Elizabeth Freeman, and she chose to work for wages at the Sedgwick household, where she helped rear their several children. She worked there for much of the rest of her life, buying a separate house for her and her daughter after the Sedgwick children were grown. After Freeman's death, the Sedgwicks buried her at Stockbridge Cemetery in the Sedgwick Pie, the family plot. The family marked Freeman's grave with an inscribed monument, and it is beside that of their fourth child, writer Catharine Maria.5
Political career
A Federalist, Sedgwick began his political career in 1780 as a delegate to the Continental Congress. He was elected as representative to the state house, and then as state senator. He was a charter member of the American Academy of Arts and Sciences in 1780.6
Sedgwick was nine years younger than John Adams, a 1780 delegate to the Second Continental Congress, attorney and state and federal politician. Sedgwick greatly admired Adams and worked for his election to the presidency in 1796.9 He was present at Adams' swearing-in as President on March 4, 1797, then serving as a U.S. Senator representing Massachusetts. Sedgwick called Adams' inauguration "the most august and sublime" event that he ever attended.10 However, certain policy disputes arose during Adams' administration, including Adams' efforts to avoid an escalation of war with France that included sending a group of emissaries to Paris in order to negotiate a lasting peace treaty to end the undeclared Quasi-War between the two countries from 1798 to 1800. When Sedgwick learned of the appointment and mission of the emissaries, "he wrote of the 'vain, jealous, and half frantic mind' of John Adams, a man ruled 'by caprice alone.'"9
Despite the differences between them, starting on the morning of March 4, 1801, the last day of Adams' term as President and the day after Sedgwick's retirement as Speaker of the U.S. House, Sedgwick and Adams rode together on the carriage trip from Washington, D.C. to Massachusetts.11
Marriages and family
Around 1767, Sedgwick married Elizabeth "Eliza" Mason, the daughter of a deacon from Franklin, Connecticut. In 1771, Sedgwick contracted smallpox which he passed on to his wife who was then pregnant with the couple's first child.12 She died of the disease on April 12, 1771 while eight months pregnant.2
Sedgwick married a second time on April 17, 1774 to Pamela Dwight of the New England Dwight family. She was the daughter of Brigadier GeneralJoseph Dwight of Great Barrington and his second wife, the widow Abigail Williams Sargent. Abigail was the daughter of Colonel Ephraim Williams, and half-sister of Ephraim Williams, Jr., the founder of Williams College.1
The Sedgwicks had ten children, three of which died within a year of birth, reflecting the high infant mortality rate of the time. They were:113
Elizabeth Mason Sedgwick (April 30, 1775 – October 15, 1827)
A child died at birth on March 27, 1777.
Frances Pamela Sedgwick (May 6, 1778 – June 20, 1842)
Catherine Sedgwick (July 11, 1782 – March 3, 1783)
Henry Dwight Sedgwick (April 18, 1784 – March 1, 1785)
Henry Dwight Sedgwick (September 22, 1785 – December 23, 1831), his grandson was a lawyer and an author Henry Dwight Sedgwick III.
Robert Sedgwick (June 6, 1787 – September 2, 1841) was a lawyer who married Elizabeth Dana Ellery, granddaughter of William Ellery, a signer of the Declaration of Independence.
Catharine Maria Sedgwick (December 28, 1789 – July 31, 1876) became one of the first noted female writers in the United States.
Charles Sedgwick (December 15, 1791 – August 3, 1856), became clerk of the Massachusetts Supreme Court. His grandson was anatomist Charles Sedgwick Minot.
During the marriage, Sedgwick frequently left his wife and children at their home in Stockbridge, Massachusetts while he focused on building his political career. His frequent absences, coupled with the death of three children and the strain of caring for numerous children (albeit with the help of her mother and many servants and slaves), caused Pamela's physical and mental health to decline.14 After Pamela's mother died in February 1791, she developed depression and began exhibiting signs of hypomania.15 She was institutionalized for a time in December 1795, but her physical and mental health continued to decline in the years following her release. She committed suicide by consuming poison on September 20, 1807.1617
Approximately eight months after Pamela's death, Sedgwick announced his intention to marry Penelope Russell.18 Russell was the eldest of ten children (six of whom died) of Dr. Charles and Elizabeth (née Vassall) Russell. Charles Russell was a Harvard University educated doctor who, in 1771, was appointed as registrar to the Vice Admiralty Court.19 Elizabeth Vassall's father Henry had been a prominent planter in Jamaica and had left his children a sizable inheritance. The Russells and Vassalls were staunch Loyalists who sought asylum in England and Antigua during the Revolutionary War.19 Sedgwick and Russell met when he represented her uncle, William Vassall, in an equity case he brought against the state of Massachusetts to win back homes and land the state confiscated during the war.20
Sedgwick's children were horrified and hurt that their father planned to marry so quickly after the death of their mother, Pamela. They also did not approve of “Miss Russell” whom they considered a spendthrift who was only interested in the Sedgwick fortune.21 Against his children's wishes, Sedgwick married Russell on November 7, 1808 at King's Chapel in Boston.13 None of Sedgwick's children were informed of the wedding and did not attend.18 Theodore Sedgwick and Penelope Russell remained married until Sedgwick's death in January 1813.22
Slave ownership
According to research conducted by The Washington Post in 2022 and the Massachusetts Historical Society, Sedgwick owned at least one slave. A July 1, 1777 bill of sale shows General John Fellows sold a woman by the name of Ton to the 30-year old Sedgwick.2324
