Klassen
A surname most likely referring to “the clan or children of Klaas,” with Klaas being a northern Dutch/German short form of Nicholas.
The #8,121 most common surname in the United States (2010 Census) — about 1 in every 75,599 Americans shares it.
Etymology
Klassen is widely understood as a patronymic surname built from the short form Klaas, a regional form of Nicholas. The ending -en is a common plural or genitival surname marker in northern Dutch and Low German naming, so the name originally meant “Klaas’s descendants” or “the family of Klaas.” In that sense, it is closely related to surnames such as Claassen, Klaasen, and Claes(s)en.
History
The surname is especially associated with Dutch and Low German speech areas and is common among Mennonite and other northern European family lines. It also spread to North America through migration, especially from the Netherlands, Germany, and related communities. In places where spellings were fluid, Klassen and Claassen could be interchanged or standardized differently in records.
