James Keith Marshall

James Keith Marshall (February 13, 1800 – December 2, 1862) was a Virginia planter and politician. He served in the Virginia General Assembly as a delegate and as a state Senator, including after Virginia declared its secession during the American Civil War.

Born to Chief Justice John Marshall and his wife Mary Willis Ambler Marshall (1766-1831) in Richmond on February 13, 1800, James Keith Marshall had several brothers and sisters. He attended Harvard College, as did all but one of his brothers, but never graduated. He married Claudia Hamilton Burwell Marshall (1800-1884), and they had eleven children, many of whom died in childhood.

Marshall served as Fauquier County's delegate in the Virginia General Assembly from 1839 until 1841 (winning re-election once, but losing in 1838). His younger brother Edward Carrington Marshall had previously held that seat. In 1853 James Keith Marshall was elected to the Virginia Senate (representing Fauquier and Rappahannock Counties), succeeding George W. Brent, and was re-elected in 1857.

After Virginia declared its secession, Marshall continued to serve in the Senate, but died in office on December 2, 1862. His cousin Alexander J. Marshall succeeded him.

James Keith Marshall was buried in the family plot in the cemetery of Leeds Episcopal Church.
