The surname Caiola may be derived from members of the roman family Gaius that settled in Marcellinara. However, the possibility also exists that it may also be derived from a Macedonian name.
Gaius (also spelled Caius) Julius Ceasar (102-44 BC) was a patrician who held important military, goverment and religious positions from the age of 20. He campaigned in Gaul 58-59 BC, and Britain 55-54 BC. He also emerged victirious from the Civil War eventually becoming "Dictator for life" in 44 BC, thus ending the Roman Republic.
