Demitrious is of Greek origin, derived from the name Demetrios, which means "dedicated to Demeter." Demeter was the Greek goddess of harvest and agriculture. The name has been popular in various forms throughout history, including Dmitri and Dimitri among others. It is often spelled with an 'h' as in Demetrius but without it as well, making it a versatile choice for parents seeking a unique yet classic name. In English-speaking countries, Demitrious gained prominence in the mid-20th century and has since been used consistently albeit not excessively, maintaining its rarity while still being recognizable.
"Demitrious experienced a peak in popularity during the late 1980s to early 1990s, with a notable spike of 10 births in 1987 and consistent numbers in the following years, reaching a total of 84 births from 1987 to 2013."
