In 1870 by taking off corners of Wood, Van Zandt, Hunt, and Hopkins Counties, Rains County was formed. Emory, the County Seat, received its name from Emory Rains, Republic of Texas leader. Emory Rains was born in Warren County, Tennessee, and moved to Texas in 1817. Emory Rains held many public offices in other Texas counties before coming to Rains County. His life was devoted to that of a public servant.
