Cornissen

Cornissen is a Dutch patronymic surname derived from the given name Cornelis, the Dutch form of Cornelius, with the suffix -sen meaning "son of." The formation reflects a common practice in Dutch onomastics, where a surname indicated descent from a male ancestor named Cornelis. The form Cornissen is most common in the Netherlands and among Dutch-speaking communities in Belgium, with occurrences in other countries tied to migration from the Low Countries.

Variants and related names include Cornelissen and Corneliszoon, among others, arising from regional spelling conventions and shifts in patronymic practice over time.

Cornissen has been recorded in civil and church registers dating back to the medieval and early modern periods. It is typically found among families with Dutch or Flemish roots, and, through migration, in populations around the world with historical ties to the Netherlands and Belgium.
