Lueretia Coffin (Mott), an American minister of the society of Friends, born in Nantucket, Jan. 3, 1793. In 1804 her parents removed to Boston, where she went to school; subsequently she attended a boarding school in Dutchess co., N. Y., in which when 15 years old she became a teacher. In 1809 she rejoined her parents, who had removed to Philadelphia, and in 1811 married James Mott, who went into partnership with her father. In 1817 she took charge of a school in Philadelphia, and in 1818 began to preach. She travelled through New England, Pennsylvania, Maryland, and a part of Virginia, advocating the tenets of the Friends and speaking against intemperance and slavery. In the division of the society in 1827 she adhered to the Hicks-ites. She took an active part in the organization of the American anti-slavery society in Philadelphia in 1833, and was a delegate to the world's anti-slavery convention in London in 1840, but, with other woman delegates, was refused membership on account of her sex. She took a prominent part in the first woman's rights convention, held in 1848 at Seneca Falls, N. Y., over which her husband presided; and since then she has been conspicuous in such conventions and in yearly meetings of Friends. She still (1875) resides in Philadelphia.
