Etymology
Di Giacomo is an Italian surname built from the preposition di, meaning “of” or “from,” plus the personal name Giacomo, the Italian form of James. Giacomo ultimately goes back through Late Latin and Greek to Hebrew Ya‘aqov, the source of Jacob and James. In surname use, it usually identifies someone as belonging to, or descended from, a man named Giacomo.
History
This type of surname developed in Italy as hereditary family names became fixed, often first as a descriptive marker for a household or lineage. In immigrant records, the space may be dropped, producing forms like Digiacomo. The name is especially associated with Italian and Italian-American communities.
