Thadeous is an uncommon yet distinguished given name of Latin origin, meaning "bold" or "courageous". It was brought into prominence by Saint Thaddeus, one of the seventy-two disciples of Jesus Christ. The name gained further popularity during the Middle Ages in Europe and has since become associated with a sense of historical and cultural significance. Spelled variously as Thadeus, Thadius, or Thaddeus, this name offers a unique choice for parents seeking an uncommon yet meaningful moniker for their child. Its variant forms provide flexibility depending on personal preference, while its Latin root adds a touch of elegance and timelessness.
"The name Thadeous experienced a late surge in popularity with six births each in 1986 and 1994, but it was not consistently favored throughout the decade, as seen by only five births in 1979. Overall, there were seventeen babies named Thadeous born during these years."
