Origin of Hilary, A Primer for Names

Hilary (also spelled as Hillary) is a gender neutral name most often given to woman that was originally derived from the Medieval Middle English words Hilarius and Hilaria. Hilarius and Hilaria go back even further, finding their origin in the ancient Roman tongue; the root meaning of Hilary as a name is both, cheerful and happy. Despite the fact that in the modernized Western world the name is given fairly exclusively to females, in ancient Rome the name was given in converse fashion, almost exclusively for men.
