History

Etymology

* As an English surname, from a pet form of Cassandra. * As an Irish surname, from Ó Cais (“descendant of the curly-haired one”), from cas (“curly”).

From Middle English cassen, from Old French casser, from Late Latin cassō, from Latin cassus (“empty, hollow”), and perhaps influenced by quassō (“to shake, shatter”).
