Tonuksens

Tonuksens is a surname of Nordic origin. It functions as a family name for people descended from a Tonuk or associated with a Tonuksen lineage.

The name appears to be patronymic, formed from the given name Tonuk, a regional form of Antonius, with the suffix -sen common in Norwegian and Danish names meaning "son of." The standard Danish/Norwegian spelling would be Tonuksen, while Tonuksens is the anglicized plural form used to refer to the family as a unit.

Historically it was found in southern Norway and western Denmark; in the 19th and 20th centuries, members emigrated to North America and other parts of Europe. In Anglophone countries, variants such as Tonukson or Tonkson have appeared.

Today Tonuksens remains a relatively rare surname; bearer communities are mostly small and localized, and it appears in genealogical databases and local histories. There are no widely known historical figures associated with the name.
