Career
The elder J.C. Gibson enlisted twice in J.R. Gilbert's company of Virginia militia for service in the War of 1812, in July 1813 and January 1814. He eventually rose in the local militia, and when General Lafayette traveled to visit President Madison at his estate, Montpelier in nearby Orange in 1824, Major Gibson led a mounted fifty man volunteer escort. Following the war, Gibson returned to farm using enslaved labor, as well as practice law in Culpeper County. Gibson's plantation was named "Dandridge" in memory of his first wife's ancestors. He owned 7 slaves in the 1820 census, 20 slaves in the 1830 census, and at least 23 slaves in the 1840 census, the last before his death. In a contested election in 1830, J.C. Gibson Sr. defeated incumbent Joseph S. Hansbrough to represent Culpeper County part-time in the Virginia House of Delegates, serving alongside Edmund Broadus. The following year, Gibson became one of the three commissioners charged with raising $1500 to build a bridge across the Rapidan River.
