History & Origin

McKinley is a Scottish-Irish Gaelic surname anglicized from Mac Fionnlaigh. President William McKinley (1897–1901) made the name a household word. The surname was borne by Scots-Irish immigrants throughout Appalachia and the American frontier.

Mckinley as a girls first name has risen steadily since the 2000s, part of the trend for presidential and political surname names for daughters. It fits alongside Kennedy, Reagan, and Lincoln as names that project strength with an American historical identity.

Did you know? William McKinley, the 25th President of the United States, gave the name national recognition. North America's highest peak was officially named Denali in 2015 after being called Mount McKinley for decades — the name Mckinley thus carries both presidential and geographical grandeur.
