This is where the majority of the myth is built. (Please see comments a few back the exact question is "where did Dracula come from then?" The blog post is a few back look under the tag of Dracula)
Otherwise there is no Dracula per say, other then the Vlad Dracul, which is from my study: the clan Dracul, and his father was also a Dracul.
The Name of this person is : Vlad Tepes.
He was born in Transylvania and was a Prince of Wallachia... returning after uprisings.
