When my parents were choosing names, they debated between Cassiopia (for the space-prostitute-turned-nurse from Battlestar Galactica) and Guinevere, of Arthurian legend.
Neither of these are popular baby names in the U.S.
Mythologically speaking, Cassiopia was the braggart queen that claimed to be prettier than Posiedon's sea nymphs. Because Poseidon was, apparently, a psycho, this resulted in him unleashing a monster on the coast of her country. Cassiopia and her husband chained their daughter Andromeda to a rock as an offering to quell the beast. Luckily, Andromeda was rescued by a convenient hero, Perseus. Happy ending! Your parents didn't get you killed!
So that story sort of sucks. However, according to the baby name sites, the name means "She whose words excel" (judging from the story, her words excel at starting trouble), so I do like that.
The name's generally considered to be rooted in Welsh, but I've also read some argument that Guinevere historically speaking was likely French.
In the end, my parents went with Guinevere. When I was a kid, I was the only Guinevere I knew. I was obsessed with Arthurian legend (yes, along with the forensic pathology. I was... well-rounded?). I didn't like my name as a child, though. It was so weird, and seriously, I was already weird enough. I didn't mind when people butchered it and called me "Jen" instead (which is derived from Guinevere).
I grew into my name, though. It helped that I got to leave my childhood home, where it seemed everyone was named Crystal or Jessica. And I married a man with a very English last name which sounds lovely with Guinevere, than my rather ethnic maiden name (which was something akin to Polishlongnameoffski). And that I just plain grew up, and being different - in any way - no longer seems like the little disaster it is at eleven.
In other words, good news, Mom: I've abandoned my childhood plans to change my name to Jane!
