I'm a bit late on this one... but everything I read is in the supernatural horror/romance genre.
I don't know if anyone is looking for anything like these (they blend all types of supernatural things), but I'll list them anyways.
Charlaine Harris - Sookie Stackhouse series
Laurell K. Hamilton - Anita Blake, Vampire Hunter series
Sherrilyn Kenyon - Dark Hunter series
Christine Feehan - "Dark" series (Carpathians - not my thing, personally)
Kim Harrison - Rachel Morgan series
L.A. Banks - Vampire Huntress Legend series
Kelley Armstrong - Women of the Otherworld series (not much about vampires in the beginning, but the vampire pops up more in later books & i'm sure she'll write about her in the future)
Katie MacAlister - vampire series
MaryJanice Davidson - Betsy Taylor series
J.R. Ward - the Black Dagger Brotherhood series
Raven Hart - "A Vampire's Seduction" is the first book of her vampire series.
Some of them are quite funny (MaryJanice & Kate Mac, particularly), some are typical romance (Feehan & Kenyon, though Kenyon writes better than Feehan, imo), and some are dark (Hamilton & Banks). Most of them combine it all. They're not particularly historical, but some have original stories and I think show where this genre is headed.
Just my .02.
