According to Jess's will in 1829, the union was childless. Two of his nephews were named Avery however. He died at age 80, the cause of death being given as old age. He left 11 slaves whose names and value were listed in the appraisal of his estate. These were Man, Peter $1,000; boy, Tom $800; woman Silvey $500; man George $750; woman Sally and boy child, Read, $1100; woman Mary $850; girl Martha $550; girl, Eliza $500; boy Jack $500; boy, David $380. The total value of Avery's estate was $8, 246.41, a substantial amount for the time (Accts. Book 1858). By contrast, his brother, Booker, who owned no slaves, has an estate valued at only $313.23 in 1846.
