I was and remain shocked to learn that every state does not teach Texas history.
I'm sure other states have something resembling history.. but really.. who cares?
Virginia history is the history of much of the early population of North Carolina, including the part of NC that was ceded to form Tennessee in 1796. Many of your own early Texas settlers and historical figures arrived via that same route over two centuries, VA to NC to TN to TX. I have many distant cousins in TX, my line stayed, been in NC since the mid-1700s, VA and MD before that. The TX bunch descend from several younger brothers who struck out for the NC backcountry and over the Blue Ridge into what became TN in 1792.
