In 1829, as a captain in the colony's militia, Jones led a company of fifty volunteers on an expedition against Waco and Tawakoni Indians from the Brazos River to the Colorado and then to the mouth of the San Saba. From 1829 to 1830 he served as alguacil, or sheriff, of Austin's colony. By 1833 he had become a client of William B. Travis at San Felipe de Austin. As a delegate to the Convention of 1833, he advocated a separate state government for Texas within the Mexican confederation. As a representative of Texas in the legislature of Coahuila and Texas in 1834, Jones, with his colleague José Antonio Vásquez and Supreme Court judge Thomas J. Chambers, issued a public appeal for a convention at Bexar to consider the establishment of a more satisfactory government for Texas. After the Texas Revolution Jones represented Austin County in the House of the Second Congress of the republic (1837-38), and in the Senate of the Third (1838), Fourth (1839-40), Sixth (1841-42), and Seventh (1842-43) congresses. He was chairman of the committee appointed to produce a flag and seal for the republic and also served as a delegate to the annexation convention in 1845.
While attending Congress in Austin in 1840, Jones became acquainted with Mrs. Rebecca Greenleaf Westover McIntyre, whom he soon married. After annexation the couple established residence at Burleigh, a plantation on the Brazos River a few miles from Bellville, where Jones became a successful cotton planter. There Anson Jones, a political ally who referred to Oliver Jones as his adopted cousin, was a frequent guest. Jones resided at Burleigh until 1859, when he purchased a home in Galveston; he remained in the Houston vicinity for most of the rest of his life. He died in Houston at the residence of Mrs. Sarah Merriweather on September 17, 1866, and was buried in the city's Episcopal and Masonic Cemetery beside his wife, who had died on Christmas Eve the previous year. The bodies of both Rebecca and Oliver Jones were reinterred in the State Cemetery at Austin in 1930.
