In 1664, Elizabeth Poole, English-American settler, founded Taunton, Massachusetts (b. 1588) dies. She was an English settler in Plymouth Colony who founded the town of Taunton, Massachusetts. She was the first woman known to have founded a town in the Americas. Poole was a well-born woman from Shute in East Devon, near Axminster. She was the daughter of Sir William Pole, who was knighted by James I in 1601, and Mary Peryam, the daughter of Sir William Peryam, Lord Chief Baron of the Exchequer. Until 2009, her family’s descendants, the Pole-Carews, lived in the Devonshire house she was born in, Shute Barton a National Trust property which is open to the public on four weekends during the year.

Elizabeth sailed from Plymouth, England in 1633 on the Speedwell with two friends, fourteen servants, goods, and twenty tons of salt for fishing provision. She intended to form a settlement and for the conversion of the Native Americans to Christianity. Although the Taunton town seal depicts Poole purchasing land from the local Wampanoag Indians, she was not actually involved in the original transaction.
