"Blend of Marc and Anthony"
The name Marcanthony is commonly a male name from the "American" origin.
Marcanthony is a compound given name formed by joining Marc and Anthony, written as a single word. Both parts are long-established English-language names: Marc is the French form of Mark, and Anthony derives from the Roman family name Antonius. The joined form has no history as a name in an earlier language and appears in US birth records from 1971, which fits a modern American formation rather than a traditional one.
The pronunciation of Marcanthony is mark-AN-thuh-nee.
