Allman
A surname often explained as meaning “the German” or “from Germany,” though some sources also connect it with Norman place-names or older Germanic name forms.
The #4,447 most common surname in the United States (2010 Census) — about 1 in every 38,704 Americans shares it.
Etymology
The most common historical explanation treats Allman as an ethnic name built on Old French and Latin forms for “Germany” or “German” (such as Alemain/Allemand, from Latin Alemannus). In English use, it likely began as a nickname for someone identified as German, or as a name for a person who had come from Germany. Some older writers also proposed other sources, including Norman place-name connections or confusion with similar Germanic personal names, so the origin is not absolutely certain.
History
19th-century surname writers repeatedly linked Allman with forms meaning “the German,” and some cited medieval spellings that point toward Norman-French influence. A smaller strand of scholarship suggested a locational origin from Allemagne near Caen, while others noted the possibility of overlap with forms such as Almond or Hallman. In English records the name appears early enough to show that several spellings and explanations may have merged over time.

Fun fact
Some early surname dictionaries treated Allman and Almond as near-variants, which shows how fluid medieval spelling and pronunciation could be.
