Theisen

Theisen is a surname of German origin. It is a patronymic name, derived from the personal name "Thies," which is a short form of "Matthias." Matthias is the German form of Matthew, a Hebrew name meaning "gift of God." Therefore, Theisen essentially means "son of Thies" or "son of Matthias."

The surname is found primarily in Germany and regions with significant German diaspora, such as the United States and Canada. Variations in spelling, though less common, might include Theis, Thiessen, and Thiesen.

The distribution of the name can offer clues to historical migration patterns of families bearing the surname. Genealogical research is often needed to trace the specific lineage and origin of a particular Theisen family.
