The whole area was originally “Carolina” http://en.wikipedia.org/wiki/The_Carolinas  I learned a lot from this link and got a chuckle out of
this description of North Carolina; [NC's nickname for many years was "a vale of humility between two mountains of conceit"; the "mountains" were Virginia and South Carolina.^[7]] Mecklenburg and Robeson are about
200 miles apart but William’s (1765) land was in Horry County, S.C. not Robeson, probably closer to 300 miles from Mecklenburg. The two Williams, (1765 and 1825) are easily confused, with Wm 1825 being the descendant of Wm. 1765.  “William Craven, 1st Earl of Craven (1608–1697)” was probably where “Old Craven County” got it’s name.
