I could not find the connection in the books I have but here is what I found in Kinfolks of Johnston County Deed Abstracts Vol. I 1759-1825 by Elizabeth E. Ross:
16 Mar. 1799 Green Hill Sr. of Franklin County to William B. Hill of Franklin County for $300., 300 ac. in Johnston County NS Black Creek, BS the Pole Cat Branch adj. Alexander Smith...
Wit: H. Potter, Henry Sewell May Court 1799
Hope this helps you.
