Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
Company A - "Sampson Rangers" - many men from Sampson County
Company B - "Nat Macon Guards" - many men from Warren County
Company C - "Brunswick Double Quicks" - many men from Brunswick County
Company E - "Duplin Turpentine boys" - many men from Duplin County
Company F - "Sparta Band" - many men from Edgecombe County
