I'm sure Evangeline will start looking like her name soon! It is a gorgeous name. FWIW, I was all for giving my DS the normal nickname for his name. Soon as he was born, nup. He's not a "Li", he's a "Liebling"!

You can also go for a nickname completely unrelated. If I shorten DS's name then it's to Wellie (the "bling" part of his name), that ended up being Duke of Wellington and now a few friends call him Duke. Which actually doesn't sound too stupid.
