Does anybody know anything about the origins of Amon Joyner of Craven County?

Tonight I've posted some items from the estate record of Amon Joyner of Pitt County, but I don't know much about the Amon Joyner of Craven County.

Who were his parents?

I'm trying to figure out how he fits into the larger Joyner picture, especially in light of him being a witness (along with Elisha Griffin) to an 1832 Craven County deed in which Samuel Street sells land to my fourth-great-grandfather William B. Morris and his brother John Morris.
