Here's another name to consider in our research. My great aunt has this in her notes:
Found a will of a George D. West, April 25, 1789 or Sept. 29, 1789 - Dec. 15, 1789, Currituck Co. Will Book 1, pp. 243-244. In his will he mentions a daughter named Lurana. Quite similar to Joshua's dauther Lurany. Could George be another brother to Joshua along with Nathanie and possibly even Thomas?
