Netto Coat of Arms and Surname Origin
Some records give Nieto; others give Netto. Both point to the same Spanish family name. Before spelling was fixed, Nieto was also written Netto. The family name meaning is “Grandson”, the same as for Nieto. Before spelling was standardised, one family could appear under several forms.
The same family of names includes Neto and Nietos.
A coat of arms belongs to a particular family line rather than to everyone named Netto, so the heraldry linked to Nieto is a starting point, not an automatic right. Want more than a summary? See the Netto family name pack.
