Kylee

Kylee is not your grandmother’s name. It debuted on the baby-name charts in the late 1970s, where Kylie has always bested its double-E version. (Other variations include Kyleigh, Kyley and Kiley.) Its etymology is unknown, but one theory is that Kylee is from Kyle, the Celtic male name that means "slim"; another theory is that it’s Australian aborigine for "boomerang."
