William T. Millican, an Old Three Hundred colonist, was born in South Carolina about 1780 and came to Texas with his parents and siblings in 1821, joining Stephen F. Austin's first colony and receiving land in this area where the community of Millican later grew up. His property was granted in 1824, and in the 1826 census he was listed as a farmer and stock raiser. Just before the Texas Revolution, he served as a delegate to the consultation at San Felipe in 1835, which endorsed a provisional government for the colonists. In 1836, as Sam Houston retreated eastward from Mexican general Santa Anna, the Millican family fled their home in the Runaway Scrape; his father, Robert Hemphill Millican, died during the flight, and after the victory at San Jacinto the family returned home from Liberty. From April until July 1836, Millican served in the Republic of Texas Army guarding the frontier and posthumously received land at this site from Sam Houston for that service. During the Republic years, he also held several public offices, including Justice of the Peace and membership on the committee appointed to choose a county seat for Brazos County, first called Navasota County, when it was established in 1841. He died in 1843 and was buried in the Weaver Cemetery in Millican.
