Murillo surname meaning

Murillo is a Spanish surname associated with localities and place-names in Spain, including places in Navarre and related regions. The name is often connected with muro, “wall,” or a diminutive landscape reference, suggesting a wall, enclosure, or small fortified feature near the original home. Morillo and Morilla are regional or related-looking forms, but spelling alone does not prove a shared family line. Independent families could take the surname from different localities. The catalog uses place with likely confidence because the habitational route is well supported, while the deeper place-name analysis is not identical everywhere.
