Thaddis is of German origin, derived from the Old High German name Thaddeus. It means "gift of God" or "God's gift." The name has been used throughout history and can be found among prominent historical figures such as Saint Thaddaeus, one of the seventy-two disciples of Jesus Christ. In literature, it appears in works like "The Pilgrim's Progress" by John Bunyan. Today, Thaddis is not a common given name, but it remains an option for parents seeking unique and meaningful names for their children.
"The name Thaddis experienced two peaks in popularity during the late 1950s, with five babies named Thaddis born each year in 1954 and 1957, resulting in a total of ten Thaddises over these years."
