Follower of Demeter or half-god
Demiyah is a modern American invention, likely created by blending the prefix 'De-' with the name Miyah or as a creative variation of Demetria. It carries echoes of the Greek goddess Demeter, who presided over the harvest and agriculture. The name has gained some usage in the 21st century as parents seek unique, rhythmic names with a familiar sound.
