This is my name, and I've never met an Englishman or American that are able to pronounce it. My American mate just calls me Spider.Something along the lines of Sveh-rreh Nyh-pan. Us Norwegians roll our R's, and pronounce the E at the end of Sverre.
You can make google pronounce it for you here: https://translate.google.com/?sl=no&tl=en&text=Sverre Nypan&op=translate
