 Near the Fitzhugh graves is a memorial marker to Long Tom, a chief of the Doeg tribe, who according to legend was killed by Susanna Alexander to save either herself or her husband John during an attack.According to Alexander family lore, he was buried at the Preston plantation cemetery and his remains were moved to Pohick with those of the family; the exact location of his grave in the churchyard, however, is not known.A memorial to John Augustine Washington, brother of George, was erected by a local chapter of the Daughters of the American Revolution in 1986, but it does not mark a known gravesite.
