Kassey is an uncommon yet charming given name, derived from the Greek 'Kassiani', which means 'boaster' or 'braggart'. It's a variant of Kassandra, the name of a priestess in Greek mythology known for her prophetic abilities.
"Kassey's popularity peaked in the late 1980s to early 1990s with 27 births per year from 1988 to 1990, but has since declined significantly, with only 9 births in 2022 and 2023."
