Trejo surname meaning
A Spanish habitational surname from Trejo in Cádiz, or a Castilianized form of the Asturian place-name Trexo.
The short story
Trejo is a Spanish habitational surname. Dictionary treatments derive it from Trejo in Cádiz province or treat it as the Castilianized form of Trexo, a place-name in Asturias—so unrelated southern and northern lines can share the modern spelling. Families from either locality carried the name as they moved within Spain and later to the Americas, where Trejo is well established in Mexican and other Hispanic populations. de Trejo appears in older documents. Place is the catalog type, and the dual habitational (Cádiz / Asturias) explanation is high confidence.
