In case you haven't noticed Ancestry has mislabeled at least some of the 1830 Census for Carteret Co. as being Beaufort in Currituck Co. and they don't take corrections. There are 18 images and Image #1 of these clearly states in the first column labeled County, Carteret County, City of Beaufort. The census contains the prominent Carteret Co. names including Benjamin Howland on p. 1. I believe I was searching p. 8 and saw Jechonias Piggott. I knew there was only 1 of him and he wasn't in Currituck Co.
I don't know if the correct Currituck Co. census for 1830 is also posted or not.
