Monimia Fairfax (1820–1875), who married Archibald Cary (1815-1854), the son of the son of Wilson Jefferson Cary (1783–1823) and Virginia Randolph (1786–1852). He maintained a winter home at 607 Cameron Street, Alexandria, Virginia, which he built in 1816. Thomas Fairfax was a follower of Swedenborg. Because of these religious beliefs, he manumitted his slaves (including the great-great-great grandfather of Virginia Lieutenant Governor Justin Fairfax), some of whom he taught a trade and sent to Liberia. This is consistent with the thinking of the American Colonization Society. Descendants
His grandson, Charles Snowdown Fairfax, 10th Lord Fairfax of Cameron (1829–1869), succeeded him as the 10th Lord Fairfax of Cameron as Fairfax's eldest son, his father, predeceased him. Another grandson, John Fairfax, 11th Lord Fairfax of Cameron (1830–1900), a physician, became the 11th Lord Fairfax of Cameron as his brother Charles died without issue.
