Hi there.
As for Deslocke's suggestions, while I can't comment on Elisabeth Bathory (never heard of), I would like to say something about the others. Dracula by Bram Stoker should be read if you're a vampire fan if only for its historical context, though I hear it is quite good. It's on my to-read list for next year, as is Interview. In the end, it'd be a good suggestions. As for Brian Lumley, I would advist avoiding him if I were you. His Necroscope universe (his vampire one) is far more modern horror with a dash of sci-fi than it is gothic horror. (Possible exception to this would be his two Lost Years volumes, but those you'd need to read several other books before to understand events that happen.) His other works lean a bit more towards Lovecraft's relm. While I love his stuff and have nearly the whole library of his books, I don't think they're what you're looking for.
Wow, enough rambling. As for my own suggestions, I would reccomend the The Anita Blake, Vampire Hunter Series by Laurell K. Hamilton. They start off a bit more action and modern horror oriented, but I'm told quickly progress to gothic horror. You even get a love triangle between the title character, and the heads of the werewolf and vampire clans in St. Louis. The series is also like
11 books long now, and she's written one or two on the side. Probably your best bet.
Final suggestions, Jim Butcher's
The Dresden Files Series. While only mentioned in name to me, it sounds like something else that might appeal to you.
Anyway, happy reading.
