Rehm
A German surname with several possible roots, often treated as a short form built from older personal names.
The #8,993 most common surname in the United States (2010 Census) — about 1 in every 84,890 Americans shares it.
Etymology
The sources mainly connect Rehm with German name-shortenings rather than a single certain word. One line of scholarship links it to older personal-name elements such as Ragin- or Raim-, while another treats it as part of a family of reduced forms alongside Rahm, Reim, and Remm. In short, it is most likely a contracted surname from an older Germanic given name, but the exact source form is not fully secure.
History
The name appears in German surname studies as part of a cluster of short forms found in southwestern and central German naming. In later genealogical use it spread beyond German-speaking areas through migration, including to the United States, where it remains relatively uncommon. Historical references sometimes group Rehm with spellings such as Ream, Reim, Rahm, and Remm, reflecting both dialect and spelling variation.
