Patrick Churchill Jack, attorney and legislator, was born in Wilkes County, Georgia, in 1808, a son of Patrick Jack, who commanded a Georgia regiment in the War of 1812. After practicing law in Jefferson County, Alabama, for three years, Jack moved to Texas in 1830 and on April 6, 1831, was issued title to one-fourth of a league of land in Stephen F. Austin's second colony in the area of present Grimes County. Jack, one of the men whose imprisonment led to the Anahuac disturbances in the spring of 1832, was a delegate from the district of Liberty to the conventions of 1832 and 1833. He later moved to Brazoria Municipality, which he represented in the House of the Second Congress of the republic from September 29, 1837, to November 13, 1838. Jack married Margaret E. Smith at Houston on October 30, 1838. He was appointed district attorney of the First Judicial District on February 1, 1840, and of the Sixth District on March 15, 1841, by President Mirabeau B. Lamar. Jack died of yellow fever in Houston on August 4, 1844, and was buried in the City Cemetery under the auspices of Holland Masonic Lodge No. 1, of which he was a member. Later his remains were removed to Lake View Cemetery, Galveston. They were again exhumed on February 10, 1942, and reinterred in the State Cemetery, Austin. In the act of the state legislature on August 27, 1856, establishing Jack County from Cooke County, it is not stated for whom the county was named. Homer S. Thrall in 1879 said it was named for the brothers, Patrick C. and William H. Jack, and this statement is generally accepted as correct.
