There's also Saint
Olga, who was the widow of a legendary Grand
Prince of Keiven Rus (medeviel Russia). She was the first christian ruler of the country. Her husband
Igor was killed, and the king of the country that killed him wanted to marry her. She managed to outsmart him and kill his army. The Byzantine Ceasar wanted to marry her too, but she had to convert first. She asked him to do it, and during the baphthism, he called her his daughter. You can't marry your daughter, right? So she got out of remarrying again. I'm not a big fan of the name, but it's one that I consider a (Slavic) classic.
