Keffer
A surname that is most likely a Germanic variant of names like Kiefer or Kefer, often connected to a person’s occupation, nickname, or local dialect form.
The #9,320 most common surname in the United States (2010 Census) — about 1 in every 88,390 Americans shares it.
Etymology
Keffer is best understood as a German surname form, but its exact origin is not certain. In many cases it is treated as a spelling variant or dialectal cousin of surnames such as Kiefer or Kefer, which can trace to German words for "pine tree," "stave/billet," or to nickname-like forms in regional speech. Because the name appears in several overlapping German-speaking surname traditions, a single literal meaning cannot be stated with full confidence.
History
The surname likely came into English-speaking countries through German immigration, especially in the 18th and 19th centuries. In North America, spellings often shifted as families adapted names to local clerks and regional pronunciation. Today Keffer is uncommon but established in the United States, with concentrations that likely reflect immigrant-descended family lines.

Fun fact
