Gwendoline

Possible nicknames could be Gwen, Wendy, Lin, Dolly...

Too LONGGGGGG.

Very chic. This is a darling spelling.

I'm not too much of a fan of this name as I think it's quite pompous - especially spelt Gwendoline. Gwendolen I think is better and less 'upper class' however I don't really like it anyway.

I knew a lovely lady called Violet Gwendoline but I prefer Gwendolen because it's neater and more authentic.

I really like this spelling of Gwendolen, it's more widely used than the other spelling, and I think it sounds more feminine and delicate altogether. This name is also much more popular in Britain. :)
