BADASH

Surnames derive from one of many different origins. Sometimes there may be more than one explanation for the same name. This family name is a Hebrew acronym (a name created from the initial letters of a Hebrew phrase, and which refers to a relative, lineage or occupation). For example, between 1787 and the 1830s, authorities in central and Eastern Europe began to force Jewish families to adopt fixed hereditary family names. Many Jews then formed European-sounding family names that were in fact Hebrew acronyms. The use of acronymics is an old Jewish custom. Famous rabbis and sages such as Rashi (Rabbi Shlomo Yitzchaki) and Rambam (Rabbi Moshe Ben Maimon, known as Maimonides) were generally referred to by acronyms based on their Hebrew titles and names.

Badash is an acronym for Ben David Shlomo ("son of David Shlomo").
