I love it. I don't think
Erzsebet Bathory was the first person I read about with the name but she was certainly one of the firsts.
I know her story pretty well thanks to one of my research modes. As for what she suffered from, we can only guess. I could do that but I get so long-winded that it might be better if I don't.
I pronounce it differently than the site lists. I say it more air-zhay-bet. Kinda. I wouldn't use it but it would make a good villain. The murderous twins
Erzsebet and
Katarzyna! Ha.
