The story
- Romance · borrowed from
- English todayCoviello
Borrowed from a Romance language, related to Covillo, likely derived from a masculine noun (thus the -o inflection). The 2010 US Census finding that the name 'Coviello' was most commonly held by white people suggests it is not a Latin-American Spanish or Brazilian Portuguese surname, though possibly from their European counterparts or Italian.
