The following information was sent to me following an e-mail request to the Library of Virginia for the pages that referenced John Clendenin from The Orderly Book of Captain Benjamin Taliaferro:
Note 21 on page 47 states that "Captain James Powers and John Clendenin, a first lieutenant, were both of the 3d North Carolina." The information on page 47 consists mainly of a Barrack Order dated February 1, 1780. It is too lengthy to be emailed, but I will send you a copy of the page by "snail mail.".
Another John Clendenin reference, this time from Ancestry.com:
