What does the name Mckinsey mean?
Mckinsey is a spelling of Mackenzie, pronounced the same way, so it shares Mackenzie's meaning and origin.
Mackenzie is a Scottish surname from Gaelic MacCoinnich, 'son of Coinneach', the Gaelic name that became Kenneth in English. Wiktionary explains that the z in the spelling came from a misreading of the old letter yogh (ȝ), which sounded like a y, so the name was originally closer to 'MacKenyie'. As a first name it has been used for girls since the 1970s, and Wikipedia notes that in North America it is now more often a girl's name.
