Sweitzer
A surname meaning “Swiss” or “a person from Switzerland,” likely brought into English from German-speaking naming traditions.
The #7,909 most common surname in the United States (2010 Census) — about 1 in every 73,810 Americans shares it.
Etymology
This surname is generally treated as a form of German Schweitzer or Schweizer, words used for a Swiss person. The core idea is ethnic or regional: originally, it identified someone as coming from Switzerland rather than describing a trade or a place in England. The English spellings Sweitzer, Sweetser, Sweetzer, and Sweetsur show how the name was reshaped in transmission.
History
19th-century surname writers repeatedly connected this name with Swiss origin, and one noted that it was already established in England by the Middle Ages. In English-language records, the spelling varies widely, which is typical of surnames borrowed from continental forms and then written phonetically. The modern U.S. form Sweitzer most likely reflects that same Germanic source.

Fun fact
Several 19th-century surname dictionaries group Sweitzer with Sweetser and Sweetzer, showing how easily foreign surnames were Anglicized into new spellings.
