There's a famous skateboarder named Natas Kaupas. Rumor was his parents were satanists as "natas" is satan spelled backwards. According to an interview with Natas himself, his Lithuanian parents thought they were having a girl and were going to name her
Natasha or
Natalia. When a boy was born they altered it to Natas, which is a surname used in Lithuania. While this doesn't completely answer your question, hopefully it'll help you on your way.
