The umlauted o is an "oe" in terms of what it stands for. We don't have an exact sound in the English language to mimic the German oe combination. Think of the famous person Hugh Hefner. HEFF-ner. Instead of saying HEFF as the first syllable say HER - fner. It would sound close to that. HERF - ner. Soften the HERF since there is no actual R but hopefully it will give you an idea.

informative and it offers me better insight on this topic
