Last name origin & meaning: Portuguese: habitational name from any of the numerous minor places
called Amaral. The place name is of uncertain etymology, probably from
the term amaral, denoting a kind of black grape (from Latin
amarus ‘bitter’). Alternatively, the origin may be a collective
noun derived from Spanish maro, amaro ‘cat-thyme’ (Latin
marum, influenced by Spanish amargo ‘bitter’).
