Di Iorio
An Italian surname meaning “son of Iorio” or “descendant of Iorio,” from a traditional given name.
The #8,891 most common surname in the United States (2010 Census) — about 1 in every 83,853 Americans shares it.
Etymology
Di Iorio is an Italian patronymic surname built from di, meaning “of” or “from,” plus the personal name Iorio. Iorio is a regional Italian form related to the name Giorgio, ultimately from Greek Georgios, meaning “farmer” or “earth-worker.” In plain terms, the surname originally identified someone as belonging to, or descended from, a man named Iorio.
History
The form is especially associated with southern Italy, where surnames formed with di plus a father’s name are very common. In records and immigration contexts it often appears as Di Iorio, though English-language documents may merge it into Diorio. Like many Italian patronymics, it became fixed as a hereditary family name over time rather than changing from one generation to the next.

Fun fact
The spacing in Di Iorio is meaningful in Italian: many families later lose the space when the name is written in Anglophone records, producing Diorio.
