I heard this somewhere and am currently crushing on it. I can’t find anything on it online, though it seems it might have (extremely) minimal use in [name]France[/name]. Seems kind of like a smoosh of [name]Gwendolen[/name] and [name]Luna[/name] - white moon, fair moon? It’s somewhat odd to have a Welsh and Latin-based combination like that.
I’m not generally a fan of made up/altered names. That said, I kind of really like the sound. It’s just different enough from the typical -lyn ending of [name]Gwendolyn[/name] to be quirky and interesting.
I like the sound but for some reason I don’t like how it looks! The ‘e’ at the end seems out of place for some reason. The only other way you could spell it would be Gwendoloon but that looks a bit silly!
I love [name]Gwendolen[/name]. Gwendolune? Not so much. The lune at the end reminds me of loon, a crazy person, not the bird. [name]Even[/name] if you say lune the french way, it still flows terribly with Gwendo.
