Actually I think that was a bit wrong. The original thirteen colony states were:
New England:
New Hampshire
Massachusetts
Rhode Island
Connecticut
The Middle Colonies:
New York
New Jersey
Pennsylvania
Delaware
The Southern Colonies:
Maryland
Virginia
North Carolina
South Carolina
Georgia
But this should clear things up a bit:
U.S. Southern States
The U.S. Southern States or The South is perhaps the most distinctive region of the United States having its own unique historical prespective, customs and cuisine. There is some overlap with The Southwest and the Mid-Atlantic States.
The South is nicknamed Dixie. A song by that title was written by an Ohio minstrel show composer, Daniel D. Emmett, first published by Phillip Werlein in New Orleans in 1859.
As defined by the Census Bureau, the Southern region of the United States includes 16 states::
Alabama
Arkansas
Delaware
Florida
Georgia
Kentucky
Louisiana
Maryland
Mississippi
North Carolina
Oklahoma
South Carolina
Tennessee
Texas
Virginia
West Virginia
