Louden is a hamlet that was begun around Lovett's store in 1839. Never regularly laid out, its origin was when Edmund Lovett (born 1815) sold small parcels of land for residences and shops. [2] The community was named after Loudoun County, Virginia, the native home of a large share of the early settlers. [2] The post office Louden once had was called Lovett's. [2] This post office was established in 1844, and remained in operation until 1907. [3] Earlier in its history, the hamlet's name was spelled Loudon.
