Were Potters Scotch-Irish in Colonial Virginia?

I found Potter information in all three volumes of Lyman Chalkley's Chronicles of the Scotch-Irish Settlement in Virginia, extracted from the original court records of Augusta County, 1745 to 1800.

From Volume One:

Page 446:  John Potter, confined for desertion, 1780

Page 230:  James Potter mentioned in the estate administration for William Steele, 15 April 17873

Page 299:  William Mark vs. Abraham Potter, account for one saddle, 21 April 1748

Page 309:  Abraham Potter vs. Robert Craven, May 1753... in 1744 ...dispute with Robert Craven

     and James Fisher regarding 350 acres on Cook's Creek..."Abraham Potter otherwise called

     Abraham Potter of Sussex upon Delaware."

From Volume Two:

Page 195:  Polly Miller, wife of Henry, has married John Potter, son of David..... she had 4 

     children by David Potter since Henry's death.... David died intestate by 14 Jun 1816

Page 218:  George L. Clemmer vs. David Potter's heirs.... 1820.... David Potter, of Rockbridge,

     died, his wife pre-deceased him, living children were:

     Margaret  --  wife of Christian Runkle

     Catherine

     Susanna  --  wife of John Wambuck or Warnburk

     Mary  --  wife of Benjamin Baltzer

     John

     Sarah  --  wife of Peter Koontz

     Eve

     Charles

     Barbara

     David (infant)

     John Potter has since died, leaving widow, Mary, and two children (Elizabeth and Sarah);  

     Sarah Potter Koontz leaves husband and daughter, Mary

     "for sogering (soldiering) money under Capt Moffett, L6.7.6"

     and Alexander to James Stewart
