In the book Wonder, the main character is called August and he is known as "Auggie" IIRC. I assumed it was pronounced org-ee or ogg-ee WITH A HARD G OBVIOUSLY! Think that's a bit ugly sounding but what about Aggie for a nn, like if she was Agnes or Agatha?
I agree with most of the other posters... it's a nice name but it isn't that easy to say.
