There were several NC Regiments as part of the NC Continental Troops at Brandywine, Germantown, and Valley Forge.

Here’s a history of one member of the 9th NC Regiment, William Polk:

William Polk was a major in the 9th Regiment, North Carolina Line, one of the regiments engaged in the Battle of Brandywine that month (Sept. 1777) and afterward in the Battle of Germantown, where he was seriously wounded. He and his regiment were with Washington at Valley Forge, following which the North Carolina regiments, weakened from illness and expiring enlistments, were reduced in number from ten to three, and William Polk was rendered a supernumerary office.

One of my g-g-g-g-uncles Thomas Francisco was a Private in the 9th NC. He died in the spring of 1778 from sickness contracted at Valley Forge.\
