Show ContentsTheunissen History, Family Crest & Coats of Arms

The German surname Theunissen originated as a short form of the Roman name Antonius (the English Anthony.) It is the name of two major Christian saints, St. Anthony (ca.250-350,) who was the father of Christian monasticism, and Anthony of Padua (1195-1231), the Franciscan monk, who became the patron saint of Padua and Portugal. In granting their children holy names, medieval parents sought to reaffirm their Christian beliefs and to secure protection from the namesake. The name Tönsing is a Low German diminutive of the name Antonius, and Tönnies is a short form, as in Tönnies Alberdes, recorded in Lippe in 1571. Other German variants include Don, Ton, Thon and Dohn. The surname Theunissen, thus, comes about as a patronymic, a surname derived from the personal name of the father.
