Ruhl
A German surname that likely developed as a shortened form of Rudolf, though other local or nickname-based explanations are possible.
The #7,468 most common surname in the United States (2010 Census) — about 1 in every 69,194 Americans shares it.
Etymology
The surname Ruhl is most often treated in German naming studies as a shortened or altered form of Rudolf. In that view, it ultimately goes back to the old Germanic elements meaning “fame” and “wolf.” Some nineteenth-century writers also noted Ruhl alongside other short forms and related spellings, which suggests it may have developed as a familiar reduced form rather than a single fixed source word.
History
The name appears in German-language surname discussions as a compact form related to Rudolf and its many regional variants. It is found in German-speaking areas and later traveled with emigrants to North America, where it remains relatively uncommon. Historical writers sometimes grouped it with other short, clipped surnames, showing how fluid these forms could be in different dialects and records.
