Adam Duncan was born in 1782, probably in Acworth, New Hampshire, where his father, John, was a successful merchant. Adam and his brother, John Duncan, moved to Barnet, Vermont sometime around 1800. Within the next few years the brothers helped form Chapman and Duncan, Mercants. Chapman and Duncan sold grain and other supplies in bulk, and occasionally sponsored cattle, grain, and gin runs to Quebec City.
Adam Duncan actively practiced law after 1812. He served as a state representative from Barnet in 1812 and 1813, was sheriff of Caledonia county from 1813 to 1815, and was a member of the 1822 Council of Censors. Duncan died on December 4, 1826, and is buried in the Stevens Cemetery in Barnet.
