The name can be traced back to various regions of Italy, including Sicily, Calabria, and Campania. In some areas, the name was also spelled as DeGiacomo or DeJacomo, reflecting local dialects and variations in pronunciation.

Historical records from the 13th and 14th centuries suggest that the name was present in various parts of Italy. For instance, there are mentions of individuals with the surname DiGiacomo in the registries of the Republic of Venice and the Kingdom of Naples.

The 17th century saw the rise of a prominent DiGiacomo family in the city of Messina, Sicily. One of its members, Domenico DiGiacomo (1620-1697), was a renowned architect and engineer who contributed to the reconstruction of the city after the devastating earthquake of 1693.
