If you didn't like the usual meaning of a name...?

That makes sense. It sounds plausible to me. I would maybe think it was better if it was hyphenated like Su-sanna, but that looks weird. You can name your kid anything you want and if it has meanings in different languages, like Brendan is said to mean "prince" but I also read that it means "smelly hair" so you obviously wouldn't be naming your child because you like the meaning "smelly hair." I'm with you!
