About the name Thaddeus

One of the twelve apostles is listed as Thaddeus in two gospels and as Jude in others, which has left the name with an oddly indistinct identity for something so ancient. Polish families have kept the Tadeusz form vigorously alive, while the English version survives mostly as Thad.

Thaddeus is a boy name of Aramaic origin, pronounced THAD-ee-us. On the NameRarity scale it scores 80 out of 100, which places it in the very rare band — a genuinely uncommon pick — most people have never met anyone with this name. Its strongest period was the 1880s.
