It so deserves to be saved from the GP box and put into the can use in real life one!
I would use it, but I prefer
Guinevere at the moment.
Guinevere is one of my top names. I have no quarms in using names others may have trouble pronouncing or spelling. And
Gwen for short is easy and nice. I just don't like the sound of it as much as
Guinevere, because Gwenhwyfar is like
Gwen and
Jennifer blended, and I'm not into
Jennifer at all.
