Vlad Tepes was born in Transylvania, which made him a native of the Principality of Transylvania.
The point which most people seem to forget about was that he was a prince of Wallachia, and his father was exiled. His father had other children, but Vlad was born in a Saxon village, which has a statue of him there.
So yes, there is a Wallachian connection to Transylvania. Not just a Hungary Royal connection to the land. Not with Bran Castle, but with the villages and cities of the Saxon people.
