mattaisen

Mattaisen is a Finnish surname. It is relatively rare and appears in Finnish genealogical records from the 19th century onward. The name is believed to derive from the given name Matti, a common Finnish form of Matthew, combined with a suffix that resembles the Swedish -sen found in patronymic and family names. This suggests that Mattaisen may have originated as a way to indicate “descendant of Matti” or to reflect Swedish-language influence in Finnish naming practices.

In modern Finland, Mattaisen occurrences are scattered and are more common in regions with historical Swedish-speaking communities, though the surname is not tied to a single locality or profession. It is present among Finnish-speaking and bilingual populations, reflecting Finland’s broader history of Swedish influence in naming.

There are no widely recognized meanings beyond its use as a surname, and it does not refer to a specific place, concept, or organization in standard references.
