Of the sea; or a modern combination name
Demarr is likely a modern American creation, often seen as a variant of Damar or a combination of the prefix 'De-' with the French root 'mare' meaning sea. It may also function as a phonetic variation of the Spanish surname del Mar. It gained some visibility in the late 20th century through athletic figures.
