Serrano surname meaning

Serrano is a Spanish topographic surname for someone from the mountains or a mountain range. It comes from a word related to sierra, the rugged chain or saw-shaped landscape, and functions as a geographic byname rather than a job title. Related spellings such as Serrana and regional Serrão may reflect language, gender, or local transmission. Several families could receive the name independently wherever mountainous terrain mattered. This catalog classifies Serrano as a place surname with high confidence because the mountain-based geographic sense is consistent across surname references.
