History
editWinchester was laid out in 1850 by surveyor Addison R. Flint, who was part of an Umpqua exploring expedition from San Francisco.[4] The town was named for one of two brothers named Winchester who took part in the expedition, probably Heman Winchester, who was the expedition's captain.[4] Winchester was the largest settlement in the Umpqua Valley for many years and the county seat until 1854, when it was moved to Roseburg.[4] Winchester post office was established in 1851, and Flint served as the first postmaster.[4] The community was incorporated as a city by the Oregon Legislative Assembly on February 20, 1891.[5]
