"Blend of Le and Marcus"
The name Lemarcus is commonly a male name from the "American" origin.
Lemarcus is a modern American formation that adds the short prefix Le- to the Roman given name Marcus. It first appears in United States birth records in 1974, and the elements are transparent: the prefix carries no lexical meaning of its own, while Marcus is the Latin name borne by a Roman praenomen. Similar prefixed forms in American naming include LaMarcus and DeMarcus.
The pronunciation of Lemarcus is luh-MAR-kus.
