I see the point you're trying to make and I can understand somewhat. One of my best friend's/colleague's last name is Jung where he's three-eights German (his mother is half German and his father is a quarter) and 5/8 East Asian. His physical appearance leans more East Asian and because of this, people who try to address him as Mr. Jung for the first time call it "/dʒɒŋ/" with a "hard J" instead of the Germanic "/YUUNG/" or "soft J." He prefers being called his first name because he always has to correct people when they attempt his last name unless when he's in Germany/Switzerland/Austria because they say "Herr Jung (yuung)"
