Cassar

• It may be traced back to the Kingdom of the Two Sicilies, incorporating the island of Sicily itself, the area around Naples, and the southern part of the Italian peninsula. The surname Cassar may have derived from the given name "Cesare," and further back from the Roman family name "Caesar." In Classical antiquity, the name "Caesar" was associated by folk etymology with the Latin word "caesaries". The Maltese Cassar coat of arms has the Latin word "SPES" inscribed on it.
• It may also derive from a fairly common surname in Italy and Sicily: Cassara, or Cassarino, possibly from a nickname "cassaio" meaning "producer of cases". However these surnames may also be derived from the given name "Cesare" or "Caesar".
