Swaim
A surname most likely from a Bavarian place name, brought into English-speaking use as a locational family name.
The #6,407 most common surname in the United States (2010 Census) — about 1 in every 58,144 Americans shares it.
Etymology
This surname is generally taken as a shortened or altered form of a place-name surname from Schwaim, said in older sources to be a town in Lower Bavaria. In that reading, the name began as a locational identifier for someone who came from that place. The resemblance to English names like Swain or Swan is probably accidental rather than the true source.
History
The name appears in older surname dictionaries as a localized immigrant or regional form, especially in Anglophone contexts. Modern U.S. bearers likely descend from families whose spelling was simplified or reshaped after migration. Because the 19th-century evidence is sparse, the exact pathway from the German place-name to the modern spelling cannot be traced with complete certainty.

Fun fact
Older surname handbooks sometimes grouped Swaim alongside several look-alike names, which makes it easy to confuse with the English surname Swain.
