Etymology
Castrejón is a Spanish surname built on the place-name Castrejón, which is associated with the Latin root castrum, meaning “fort” or “castle.” The ending -ón in Spanish can form a place-name or an augmented form, so the name likely points to a locality connected with a castle, fort, or fortified site. In surname use, it would originally have identified someone who came from that place.
History
This is a toponymic surname from Spain, and surnames of this kind were commonly adopted by people identified by their home village or estate. It is found in Spanish-speaking regions and later in the Americas through migration from the Iberian Peninsula. The accented form Castrejón is the standard Spanish spelling, though the accent is sometimes omitted in records and databases.
