Possibly a modern combination of De and Maya
Demaya is a modern American creation, likely formed by adding the popular prefix 'De-' to the name Maya. Maya itself has multiple origins, including Sanskrit meaning 'illusion' or 'magic', and Greek meaning 'mother'. As a contemporary coinage, it represents a blend of traditional roots and modern stylistic innovation.
