Mckinnley

Meaning & origin

Mckinnley, a variant spelling of McKinley, entered the U.S. baby name charts in 1994 as a feminine given name. It reached its peak popularity in 2011, but has since been declining in use. By 2025, it ranked 8,362, with approximately 1 in every 133,939 newborn girls receiving the name. The name's trajectory shows a sustained downturn over the past decade, reflecting broader shifts away from surname-style names. Despite its rare usage, Mckinnley remains a distinctive choice that connects to Irish and Scottish heritage through its etymological roots in the Gaelic name Cináed, meaning 'white warrior' or 'fair hero.'

Mckinnley is a variant spelling of McKinley, an Anglicized form of the Gaelic surname Mac Cináeda, meaning 'son of Cináed.' Cináed itself is an ancient personal name derived from elements meaning 'born of fire' or more commonly interpreted as 'white warrior' or 'fair hero.' The surname McKinley has been used as a given name in the United States, particularly for girls, since the late 20th century, following the trend of using Irish surnames as first names.
