Meaning & origin

Theodus is a rare masculine name first recorded in 1912, the year it also achieved its peak usage (with a handful of births). Since then, it has remained stable but uncommon, with no recorded spike in popularity. The name does not appear in any top state data, suggesting its usage was isolated. Likely a variant of Theodorus or Theodore, Theodus offers a distinctive alternative for parents seeking an unusual, historical-sounding name without a long tradition. Its exact origin remains unclear, but its similarity to established names may appeal to those drawn to classical forms.

Theodus is a rare name that first appeared in U.S. records in 1912, possibly a variant of Theodorus, the Latin form of the Greek name Theodoros, meaning 'gift of God.' However, given its isolated early usage and lack of historical depth, it may also be a modern respelling or invention. No clear derivation is attested.
