Sachs
A surname that most often points to a Saxon or German ethnic origin, though some older writers linked it to Isaac or to the word for “sack.”
The #4,866 most common surname in the United States (2010 Census) — about 1 in every 42,597 Americans shares it.
Etymology
The strongest historical explanation is that Sachs is the German word for a Saxon, ultimately from Latin Saxo/Saxones and Old Saxon forms meaning “Saxon.” In this sense, the surname began as an ethnic label for someone from Saxony or of Saxon stock. Some 19th-century writers also suggested a connection with Isaac or with a word for “sack,” but those ideas appear secondary or less likely in the sources provided.
History
German surname dictionaries commonly treat Sachs as an ethnic name, and the form is widespread in German-speaking regions. In English-language reference works, it was sometimes recorded alongside similar-looking surnames and occasionally confused with other names, which led to competing guesses. The name is also found in Jewish and immigrant family lines where Germanic surname forms were adopted or retained.

Fun fact
One source explicitly glosses Sachs as “Ger. Saxon,” showing how directly the surname was once tied to regional identity.
