Let me clarify my previous comment on pronunciation. This is the nickname I go by. Even though I live in an English-speaking country I use the German spelling due to my German background. In English it gets pronounced like the standard English version spelled Susie, SOO-zee. In the southern German dialect I grew up with it's the same, SOO-zee. In standard German it would indeed be pronounced ZOO-zee, as indicated on here (though that sounds foreign to my ears).
