Costantino
An Italian surname from a personal name meaning “constant” or “steadfast.”
The #9,593 most common surname in the United States (2010 Census) — about 1 in every 91,129 Americans shares it.
Etymology
Costantino is the Italian form of Constantine, ultimately from the Latin name Constantinus, which comes from constantia, meaning “steadfastness” or “constancy.” In surname use, it usually began as a patronymic or family-name formation from a given name borne by an ancestor. The deeper roots are linked to the late Roman and Byzantine world, where the personal name was widely used.
History
The surname is especially associated with Italy and Italian diaspora communities. It likely developed independently in several places from men named Costantino, rather than from a single founding family. As with many Italian surnames based on saints’ or classical personal names, it spread through migration to the Americas and elsewhere in the modern period.
