Yes, in the region of Translyvania, which extends over into Romania. Elizabeth Bathory was known as the Blood Countess, because she had hundreds of young girls killed and bathed in thier blood, believing that by doing so she could maintain her beauty forever. She was mentally disturbed, and also probably a lesbian(she was said to be lovers with some of the women with helped her capture and entice victims, and she was said to have had sex with some of her victims before killing them)

But because she was of the nobility, and was kin to several important leaders (including the King of Poland) no one stepped in to stop her crimes, until aroiund 1611. By then, she had moved on to victims of noble status. At any rate, stories of the numerous missing girls and tales of the unspeakable acts which went on inside her castle were legion, and finally her brother was ordered to investigate. her castle was stormed, and her crimes were revealed. They found several recent victims hanging up, they had been tortured. they also found dozens of others in the dugeons, who were waiting thier turn. they also found a book listing the number of victims(at least 650, some say it was 800). But due to her nooble status, she was sentenced to life imprisonment, her accomplices had thier fingers ripped out and were burned alive. She was walled up inside her castle, and died 4 years later. Bathory was cited as an inspiration for the vampiresses in Dracula, and legend says she was a vampiress herself. Her family was related to Vlad Tepes as well.
