Meaning and origin of Mckinley
Mckinley is a Scottish and Irish name that means “son of Finlay, 'fair warrior'”.
McKinley is a Scottish and Irish surname from Mac Fhionnlaigh, son of Fionnlagh, a Gaelic name made from fionn, fair, and laoch, warrior. The surname became famous in the United States through President William McKinley, and his name was given to Alaska's highest peak, also known as Denali. As a first name it was once used for boys but is now more common for girls. It sounds cheerful and spirited, with a bouncy three-syllable rhythm.
