Here's a breakdown of its possible meanings:
* Topographical: It likely refers to someone who lived near a moorland or heatherland area.
* Patronymical: It could also be a patronymic surname, meaning it is derived from a given name, in this case, "Soria." This would suggest that the original bearer of the name was named "Soria" and his descendants took on his name as their surname.
The name Soriano is common in Spain, Latin America, and the Philippines, due to Spanish colonization and migration.
