Demeturis is of Greek origin, derived from the Greek god Demeter. It is often spelled Demetrios, but the variant Demeturis is less common. The name means "follower of Demeter," the goddess of harvest and agriculture in ancient Greek mythology. Demeturis was popular among early Christians due to its association with Saint Demetrius, a martyr from the 4th century.
Demeturis had 12 babies named between 1973 and 1977, with an average of one birth every two years during this period.
