Guenevere

I like Guinevere better.

I like this spelling a lot, but I prefer the other one by a little bit.

Guenevere is a lovely name, and though a legitimate variant of Guinevere it looks misspelt to me.

Too many E's.
Just stick with Guinevere.

Guenevere is the original version of the much overused Jennifer. I think it's a beautiful name that should be considered by parents who like Jennifer, but realize it's become so common it's a cliche. Maybe they're put off by the fact that Queen Guenevere was unfaithful to King Arthur, though.
