Present throughout Italy, Casale is mainly located in north-western Italy and throughout the south, particularly on the Tyrrhenian coast of southern Italy, while Casali is widespread throughout the central north. These surnames should derive from very common toponyms such as: Casale (MI) - (PR) - (MN) - (CE) - (GR) etc. or Casali (AQ), but can also be originated from nicknames linked to the locality (those of the farmhouse).
