D'Onofrio
An Italian surname meaning “son of Onofrio,” ultimately from the saint’s name Honorius/Onuphrius.
The #5,769 most common surname in the United States (2010 Census) — about 1 in every 51,423 Americans shares it.
Etymology
D'Onofrio is an Italian family name built from the personal name Onofrio, with the prefix D' meaning “of” or “from.” The given name Onofrio corresponds to Saint Onuphrius, whose name passed into Italian through late Latin and Greek forms. In this sense, the surname originally identified someone as “belonging to, or descended from, Onofrio.”
History
The surname is found chiefly among families of Italian origin, especially in southern Italy, where saint-based personal names became common hereditary surnames. Like many Italian surnames formed from a father’s given name, it spread through emigration to the Americas in the 19th and 20th centuries. In English-language records the apostrophe is often dropped, producing forms such as Donofrio.
