Jethro New (September 20, 1757-July 25, 1827) was an 18th century American frontiersman and Continental Army officer during the American Revolutionary War, at one time serving as an aid to General George Washington. He was a prominent settler in North Carolina and Kentucky as well as being among the first families to arrive in Jennings County, Indiana.
Of his twelve children, his son Hickman New was a minister of the Disciples of Christ and his son Robert New was the first Secretary of State following Indiana'a admission into the United States. His youngest son Jeptha Dudley New was a state representitive of Indiana in the United States Congress from 1879 to 1881.
Following the war, he married Sarah Bowman in North Carolina and together had 12 children. Sarah Bowman was one of the daughters of Virginia pioneer George Bowman and, in 1785, he moved his family to Kentucky County to join his brothers-in-law Abraham, Isaac and John Jacob Bowman who had settled in the area nearly a decade before. After his wife died in 1813, he and his family moved from Gallatin County, Kentucky to Jefferson County, Indiana in 1822 and later to Vernon, Indiana. He died there in 1827 and later buried in the lower part of Vernon Cemetery.
