Bahr
A surname with Germanic roots, often connected with the old personal name Ber/Bar and sometimes treated as a short form of names built on that element.
The #4,589 most common surname in the United States (2010 Census) — about 1 in every 39,936 Americans shares it.
Etymology
The historical sources point to Bahr as a German surname related to older name forms such as Ber and Bar. In early Germanic naming, these short forms could be used as personal names and later become hereditary surnames. Some older reference works also connect the name with broader Germanic name-stems found in forms like Bero and Baring, so the surname is best understood as a shortened or descendant form of an old personal name rather than a descriptive word.
History
The name is documented in German surname traditions and appears in older onomastic discussions alongside related forms such as Bahr, Beer, Ber, and Baring. In English-language records it is relatively uncommon, but it has been carried into the United States through German-speaking immigration. Because the documentary tradition is old and somewhat mixed, the exact line of derivation may vary by family.

Fun fact
Older surname dictionaries sometimes group Bahr with a family of very short Germanic name-forms, showing how a single syllable could later generate several different hereditary surnames.
