There is quite a bit of history from the “earliest” Colonial Period too.
That early history has not been so overlooked, deliberately denied or deemed questionable and then appropriated for another state or region. I guess early settlers to the Colony of NC were just too backwoods to be held up as exemplars in the blossoming national mythos, lol. That, and the squabbling of our Lords Proprietors was just a little unseemly.
But then, you have Virginia, a powerhouse of economic and cultural might in every colonial era, and the same fate befell them, with Jamestown. Plymouth gets the credit, not them. I guess yet another group of squabbling English businessmen looking for fortune weren't quite so compelling as Puritans looking for sanctuary.
So, I sense a bit of bias, tracing back to the Civil War era, perhaps?
The origins of the story that is topic of this thread seem well verified, so I can't honestly say that this is the case, here. That Sybill Luddington has a US Postal Service commemorative stamp, and a statue in her honor is nice. But, there are others, equally brave and daring, and not entirely unknown to history, who have received no such honor. I try to commemorate them in my own small way.
I've always been intrigued by this particular story, especially what Betsy Dowdy is reputed to have said to her little Banker pony, what she called her: "Black Beauty." No book or movie credits or acknowledgement for that, that I am aware.
