Of Greek origin.

From the Greek word “θείον”, meaning divine, holly, godly.

It is also associated with the Greek name Theodore, which means “gift from God”.

Theon of Smyrna was a Greek mathematician and philosopher, influenced by the Pythagoreans.

The name’s popularity has risen the last couple of years, due to fictional character Theon Greyjoy, from the “Game of Thrones” television series.
