During the siege of Boston, Betsy Revere made flags for Boston's Castle William, the state's first naval vessel, and later for Colonel Proctor's Artillery Regiment. Later in life she was active with Trinity Church's Charitable Society, assisting widows and their families.
On 14 April 1757 Betsy married silversmith Paul Revere, in the First Church of Boston, and they set up house on North Square in Boston. She bore ten children, eight sons and two daughters, five of whom died before reaching adulthood. In February 1775 the Reveres' home was damaged in a fire and they temporarily lived in Reading.
Shortly before the Battle of Lexington and Concord, Betsy Revere left Boston with her youngest son, Joe Warren Revere, to temporarily stay in Reading, and it is believed that she met with her husband for the purpose of discussing the movement of troops. Later that night Paul set out on his famous midnight ride to warn Samuel Adams and John Hancock that the British were moving, and at least one historian contends that Betsy Revere, who was staying with relatives on the road that the troops would soon be traversing, was a part of the network that helped spread the warning.
It has never been proven that Paul did in fact ride to warn the militia, but the ride was made famous 50 years after the event by Henry Wadsworth Longfellow in his epic poem "Paul Revere's Ride."
Betsy was well-known as an artist, and the State House in Boston features three of her watercolors, the only paintings hanging on its walls by an 18th-century artist.
Upon her death in 1818, she was buried at the Granary Burying Ground, in Boston, her grave marked with the following epitaph:
>_"In Memory of / Mrs. Elizabeth Revere, / Consort of the late / Paul Revere, Esq., / Who died Feb'y. 11th, 1818 / Ætat. 86. / She was endowed by nature with a superior understanding, / and her various Accomplishments / rendered her a most amiable companion; / her life was a continued display of conjugal affection, / maternal tenderness, / and every female virtue."_
