Williamson was platted about 1870 by land owner Samuel Z. Hawbaker,[3] and may be named after Hugh Williamson, the patriot contemporary of Benjamin Franklin, both whom were Founding Fathers of the United States. Another possibility is that the community is named after an unknown local denizen surnamed Williamson, perhaps an early postmaster of the local post office that has been in operation at Williamson since 1872.[4]
