The Kuhne Family Name
The spelling Kuhne grew out of Kuhn, a German surname with a long paper trail.
The extra “e” in Kuhne is a spelling habit rather than a different name.
A coat of arms belongs to a particular family line rather than to everyone named Kuhne, so the heraldry linked to Kuhn is a starting point, not an automatic right. Want more than a summary? See the Kuhne family name pack.
