I have two copies of Coats of Arms of the Malerbi Family from Italy.My great grandfather Carlo left Lucca in the late 1800's for California.One coat of arms is from Milan, copied 1836 and full of worm holes.(But well framed now!) The other is from Studio Armeristico Storico Genealogico, Napoli.The only similarity of the Coat of Arms are the Three Stars. I have translations of both if you would like to have this info.
The napoli coat of arms lists all the famous or infamous Malerbi's to 1926.
