The surname Marigliano is an Italian surname of toponymic origin, derived directly from the name of the locality of Marigliano, situated in the present-day province of Naples, in the region of Campania.

According to the surname studies, this kind of surname arose in order to identify people originating from a particular place, especially when they moved to other localities. In this case, Marigliano originally designated whoever came from that town.

Historical and geographical context

The locality of Marigliano forms part of the historical area of the Agro Nolano, a zone of ancient Roman occupation and of strong demographic continuity throughout the Middle Ages. This favoured the early fixing of surnames based on the place of origin.

In the repertories of E. Rossoni, Marigliano appears repeatedly as a centre of diffusion and concentration of numerous Neapolitan surnames, which confirms its historical relevance within the Campanian onomastic system, although without a specific entry being developed for the surname itself.

These surnames do not indicate kinship among themselves, but rather a shared geographical origin.
