Hereditary family names gradually came into usage in Italy beginning in the 10th and 11th centuries. Italian
were developed according to fairly general principles and they were characterized by a profusion of derivatives coined from given names. The surname Petrini came from the
Pietro, which is itself from the Latin "Petrus," and the Greek "Petros," meaning "rock."
The surname Petrini was first found in throughout Italy, although they most frequently appear in the southern Italian regions of Puglia and
. One line of Petroni di Siena were on record from the 13th century.
