Edward Carrington Marshall (January 13, 1805 – February 8, 1882) was a Virginia farmer, planter, businessman, and politician.

That year Marshall also sold the home constructed for him and his new wife after their wedding ("Carrington") and moved to a farm about a mile away in Markham near the new line).

To reduce lease payments to the O&A, the MGRR began raising funds to construct an alternate line between Gainesville, Virginia and Alexandria.

Portions of the unfinished MGRR Independent Line also served as earthworks for Confederate troops at the Second Battle of Manassas.

Furthermore, his son James Keith Marshall, an 1860 VMI graduate, was commissioned a Confederate officer and died at the Battle of Gettysburg.

Meanwhile, Marshall secured a place in the Pension Office in Washington D.C. during the administrations of Ulysses S. Grant and Rutherford B. Hayes.

He had built a new home, "Innis", in 1871-1872, and his family continued farming, and he visited during breaks from Washington, as well as also assisted in the nearby school run by his friend Dr. Jacquelin Ambler.

Both Carrington and Innis survive today, and since 2007 have been designated contributing buildings in the John Marshall Leeds Manor Rural Historic District.
