John Carter, in the books, repeatedly states that he has no idea how old he is and can't remember his childhood, yet he also repeatedly and proudly cites that he's from Virginia, or he's referred to as a "Virginian Gentleman."
Now, being a native 6th generation Virginian, I love reading that, but how can he be sure he's from Virginia if he can't remember his childhood, much less his parents or anything about his birth?
