My cousin's name is Annmarie (well, she's my dad's cousin, but still). Everyone has always called her Annie - I suspect she only got "Annmarie" when she was in trouble, lol! Anyway, it took me years to discover that her real / legal name was Annmarie, since I'd only ever known her as Annie.
As for spelling, I actually prefer the Annemarie spelling, since I've always found the "two Ns and an M" to look terribly awkward smashed together. But I'm not really one for "combination" names, anyway, so I doubt I'd use this in real life. On a character, maybe.
