Williamson Simpson Oldham Sr. (June 19, 1813 – May 8, 1868) was an American politician who served in Arkansas state government, and as a Confederate States Senator from Texas from 1862 to 1865.
In 1848 he resigned to run for Congress, but was defeated, thereafter moving to Austin, Texas.
In Harry Turtledove's 1994 alternative history novel, Guns of the South, a "Congressman Oldham" from Texas is mentioned as sponsoring a bill to re-enslave freedmen in a victorious Confederacy.
Since the setting was the time of the 2nd Confederate States Congress, it is likely that Turtledove was referring to Senator Oldham.
