Rosenbaum
German surname meaning “rose tree” or “rose bush,” originally a decorative name or house sign.
The #3,791 most common surname in the United States (2010 Census) — about 1 in every 33,081 Americans shares it.
Etymology
Rosenbaum is built from German Rosen, the plural or combining form of Rose, and Baum, meaning “tree.” In older German usage, especially Middle High German, it could refer to a rose tree or rose bush rather than a literal tree species. The name was later taken as a surname, and in some cases may also have come from house names or signs featuring a rose tree.
History
Historical German surname dictionaries treat Rosenbaum as part of a larger group of ornamental or sign-based names built with Rosen- plus a second element such as tree, hill, field, or flower. The name appears in medieval and early modern German contexts, including house names in Strasbourg, and it also spread as a Jewish surname in German-speaking areas. In English-language records it is found chiefly among families of German or Central European origin.
