I see no Stallings for any of the names you have in Duplin. Here are the only names I've found in association with Stallings,which was in Chowan County,NC:
Deek Dingley - a former slave of Jochabod Jordan, who had been freed in about 1795, but Mr. Jordan tried to reclaim him as a slave in 1798.
There were several people with the Stallings surname who signed a petition swearing to the character of Mr. Dingley.
Miles Stallings, Elias Stallings, Zachariah Stallings, and probably John S(t)allings.
