I'll post some info on a second plot that mentions Samuel Cunningham that is adjacent to the one in my previous post.
NC State Grant Surry NC File No. 83, Grant 81, Entry Book 1 108, Entered May 25, 1778, Warrant Sep 04, 1778, Surveyed Sep 23, 1778, and issued Sep 20, 1779.
50 Acres on Cunningham Spring Branch (Deep Creek)
The Surry NC Deed for this is in Book A, 293,294
Warrant Abstract: No. 108 for Henry Speer 50 acres on the head of Samuel Coningams spring branch, including part of said Coninghams improvement for complement 4th September 1778.

I'll try to attach a couple of images so you can see where these are on Deep Creek in present day Yadkin Co NC
The 270 acre lot appears to be split by Deep Creek and Highway 421 may cross its upper boundary
Let me know if you have questions. I'm not related to this family, just did a lot of land research in this area.
