Leal surname meaning

Leal is an English, Spanish, and Portuguese nickname for a loyal or trustworthy person. It comes from Old French leial and from Spanish and Portuguese leal, “loyal” or “faithful to obligations,” ultimately from Latin legalis, related to lex, “law.” The byname praised reliability rather than naming a trade or a village. In Iberian records the same adjective became a hereditary surname; English lines reflect the overlapping medieval French vocabulary of loyalty. Nickname is high confidence for that shared “loyal person” sense that DAFN assigns across the English and Iberian streams.
