I am impressed (and a little bit spooked :o) that you know why Dracula's parents did not name him Herbert
Seriously, though, your point is a little bit off, because Dracula was a real person. Count Vladimir
) Draculea Tepes III (1437-1476) was a Romanian nobleman who ruled the Transylvanian county of Wallachia. He was named Vlad
after his father, Vlad
"Dracul" Tepes II, and his middle name, Draculea (the original spelling of Dracula), means "son of Dracul". Dracul was his father's nickname, the name of his family's castle and, as far as I remember, the Romanian word for "a dragon". Dracula was deprived of his rightful throne at birth, which caused him to grow resentful. When he got old enough, he allied with the Moldavian king and regained the rule of Wallachia. Once in power, he turned into a tyrant and got notorious for being bloodthirsty and extremely fond of torturing his enemies (a lovable person indeed!). The stories of his cruelty spread around quickly and created a lot of legends among the superstitious folk of Transylvania. That is how the legend of the vampire Dracula originated.
P.S. Some sources claim that the name Dracula ("son of the dragon" where dragon = devil) was bestowed upon Vlad
by the Catholic church which did not like his anti-catholic actions.
