Meaning & origin

Hillary saw its peak popularity in 1992, when it ranked among the top names, largely coinciding with political prominence. Since then, its use has fluctuated, with a period of decline followed by a modest resurgence beginning around 2019. The name was first recorded in U.S. data in 1922, and its highest concentrations have historically been in states like Texas and California. Despite its checkered popularity, Hillary retains a classic feel and a positive etymological association with cheerfulness.

Hillary is the English form of the Latin name Hilarius, from 'hilaris' meaning cheerful or merry. It was historically a masculine name, borne by several saints including Saint Hilary of Poitiers. In the 20th century it transitioned to primarily female use, particularly in the United States.
