Dear Betty et al; I have amended subject line. I have been to the State Archives and can verify that the ancestry.com database of NC wills is indeed wrong. The 1780 will is of a "John Adcock". I have a copy. Even thought John does not appear in the indexes of tax lists on ancestry.com this is because there lists are incomplete John Adcock first appears in 1747. This is as abstracted in a publication in the archives: John Adcock of Granville Co., North Carolina, January 31st 1780 "being sick and very ancient". All that I have a "rite" or property to Edward Conneway (sic) except one shilling per each of the rest of my sons and daughters. Lenard Adcock, John Adcock, Bolen Adcock [note not Boulton] Jesheled (sic), Sarah and Elizabeth, Robt Adcock. If the said Edward shall comply to assist John Adcock in his "feble" old age, then all goods and chattle to be his right and property forever. Wt. Richard Brinkley, Laban (X) Oakley. February Court 1780 proved by oath of Richard Brinkley and Laban Oakley. Administration granted to Edward Connaway.
Only one thing still troubles me "Edward Connoway" is definitely by implication "son" of John Adcock, however he is identified as "Edward Connaway" (not Adcock) even in the probate record. In this time period the term "in law" did not have its modern meaning and in laws were often just referred to as "sons" in wills. One thought - is it possible that Edward Connaway was by a previous marriage of John's wife - this could explain his name appearing in this form.
