Ernst
A German and Dutch surname from a word meaning “earnest,” “serious,” or “zealous.”
The #1,969 most common surname in the United States (2010 Census) — about 1 in every 16,815 Americans shares it.
Etymology
Ernst comes from Old High German and Middle High German words meaning “seriousness,” “earnestness,” or “zeal.” The surname likely began as a nickname or descriptive personal name for someone thought to be grave, resolute, or sincerely committed. In some older Germanic name studies, the same root is linked to the idea of determined struggle or earnest combat.
History
The name is long established in German-speaking areas and also appears in Dutch records. It can function both as a surname and as a given name, which helps explain its spread. In modern usage it is especially common in German-language regions and in communities of German descent abroad.

Fun fact
19th-century scholars sometimes connected Ernst with an old Germanic idea of “earnest combat,” not just plain seriousness.
