The one at the top left and the one on bottom are both from the Guilford family (Guilford Stemmed, Archaic) and are very common in your area. The two at the top right are probably Morrow Mountain, the one in center being pretty classic for the type (Archaic). Funny how you mention the Gary point Atlantis - the MM were actually called Gary over east until identified as a new type from North Carolina specimens in the early 60's.
Cliff Jackson is the man to contact on North Carolina points. He's from Warrenton, a veteran collector and a good friend. If you ever make it over that way, he has a mill that he's pretty much converted into a museum - drop in and give him a titty twister for me. He's also the president of the AACA and you can reach him from that website.
