About the name Thaddeus
Thaddeus belongs to the Biblical & Christian and German tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess.
In the United States, Thaddeus first appears in Social Security records in 1880. It climbed to its best-ever rank of #307 in 1918, and in 2024 284 babies received the name — 25,739 in total since 1880. Those are the official counts, not estimates.
