Thadius is a spelling variant of Thaddeus, a name that reaches English through the Latin Thaddeus and the Greek Thaddaios, the form used in the New Testament for one of the twelve apostles. The two spellings differ only in that the doubled d of Thaddeus is reduced to one, so the name itself is the same rather than a separate formation.
