I adore the name McKinsey. I think the name sounds very prestigious. I like a lot of the last-names-as-first-names, this being one.  

McKinsey as a surname is a fairly rare variant of Mackenzie. Without the "mac," Kinsey is an English surname, derived from a personal name composed of the Old English elements cine "royal" and sige "victory." As a first name, it became popular for girls in the late 20th century following trends of Mc-names.
