Keim
A surname with several possible roots, most often linked to a German personal name or nickname, and sometimes to place-name forms in German-speaking areas.
The #4,565 most common surname in the United States (2010 Census) — about 1 in every 39,741 Americans shares it.
Etymology
Keim is most plausibly German in origin, though the exact source is not certain. In German, keim can connect to old personal-name elements or nickname formation, and surname writers have also treated it as a shortened or altered form in compounds rather than a single transparent word. Because the evidence is mixed and the surname appears in different regional naming traditions, a single literal meaning cannot be stated with confidence.
History
The name is well attested in German-speaking areas and later appears in the United States through immigration. Historical surname references also show it alongside other German family names, suggesting it belongs to the broader Central European naming stock. In some places it may also be influenced by local place-name usage or by dialect spellings that reduced or reshaped longer forms.

Fun fact
In German surname dictionaries, Keim is sometimes grouped with other short forms whose exact origin is hard to pin down, which is why it often appears in the “uncertain” bucket.
