Tim, I have two entries of Wills of Edgecombe NC 1733-1856 of two DAVID SCARBROROUGH. There are DUNN names listed. I will check later for DUNN wills, I did find ADDISON listed, and am sending you the two entries. Passing along..........

In this will the following name is listed, but it does not give relation--JOHN SMITH
Then JOHN DUNN and his wife EASTER/ESTHER(?)
Executives of will: MILES SCARBROUGH & WILLIAM SCARBROROUGH.
hope this helps you in some step of your searching and the pieces of the puzzle can be found.
