Diehl
A German surname most often understood as a short form of names based on the old Germanic element for “people” or “folk.”
The #1,916 most common surname in the United States (2010 Census) — about 1 in every 16,410 Americans shares it.
Etymology
Diehl is generally treated as a short form or contracted form of older Germanic personal names, especially names built with the first element thiud-/diet-, meaning “people” or “folk.” In older surname studies, it is often connected with names such as Dietl, Dietrich, Diebold, or related forms, though the exact pathway can vary by region. In some cases it may also have been influenced by the common German surname pattern of shortening longer given names to a one-syllable family name.
History
The name is found in German-speaking areas and became common enough to spread widely with German migration. American surname writers in the 19th century noted Diehl alongside other German names that had already entered the United States, especially in cities with substantial German communities. In modern usage it is well established in the US and remains strongly associated with German ancestry.
