Thiébaud

This name derives from Old High German “Dietbald,” which in turn derives from the Ancient Germanic “Þeudobald / Theudobald” composed of two elements: “*þeudō” (a people, a nation) plus “*balðraz” (power, strength, brave, bold, able-bodied), meaning “bold people, valiant among the people.” In Medieval Latin, this family of names was further influenced by many names of Greek origin starting in “theós (θεός),” meaning “god.” 1) Teobaldo Roggeri (1099–1150) is venerated as a saint by the Catholic Church. 2) Saint Theobald of Marly (French: Saint Thibaut, Thibault, Thiébaut) († 1247) was a French abbot and saint. 3) Theobald (Theudebald, Theodolt, Theodoalt) was the Duke of Bavaria from at least 711 when his father Theodo associated him with his rule at Passau or Salzburg.
