Theres is a German (Upper German and Swiss) variant of Therese, itself a form of Theresa. The name derives from the Spanish and Portuguese Teresa, first recorded as Therasia, borne by the 4th-century Spanish wife of Saint Paulinus of Nola. The etymology is uncertain; possibilities include Greek theros ("summer"), therizo ("to harvest"), or from the Greek island of Therasia (part of Santorini). During the Middle Ages, the name was largely confined to Spain and Portugal. It gained widespread Christian popularity after the 16th century due to Saint Teresa of Ávila, a Spanish nun and reformer. Another important bearer was the Austrian Habsburg queen Maria Theresa (1717–1780), whose inheritance sparked the War of the Austrian Succession. In the German-speaking world, the form Therese and its variants like Theres and Theresia became established, though Theres itself is less common than Therese or Theresia today. Cultural and Geographic Association The name Theres is also homonymous with a municipality in Bavaria, Germany, once the site of Theres Abbey (demolished in 1809), which may have reinforced the name's usage in that region as a given name or place-derived surname. Notable Usage While Theres does not have as extensive a history of notable bearers as its parent forms, it remains a recognized variant in German-speaking Switzerland and parts of southern Germany. Related forms in other languages include Terese (Swedish), Tereza (Slovak), Teresa (also Swedish), Terezija (Slovene), Tena (Croatian), and Czech Terezie.
