Is there a Martocci coat of arms?
No authentic coat of arms, crest or noble recognition has been found for Martocci, Martoccio, Martocchio or Martoccia. The two standard Italian and European armorials were read in full: Crollalanza's Dizionario storico-blasonico (all three volumes) runs straight from Martorelli to Martucci, and Rietstap's Armorial Général skips from Martius to Martonie. The red shield with a rampant lion that some "surname crest" websites sell as "Martocci, noble of Foligno" is a misattribution: its text is copied word for word from the site's entry for the Bartocci family of Foligno, whose own arms are recorded as unknown ("stemma ignoto"), and the site says such entries are machine-generated. Heraldry belongs to a specific family line, not to everyone with a surname, so a crest offered "for the Martocci name" should not be treated as the family's.
High that no arms appear in the major armorials; Spreti's Enciclopedia storico-nobiliare could not be searched directly
Where this site's colors come from
Because no family arms exist, the site's palette is taken from the official arms of the Region of Basilicata, the homeland of the closely related Martoccia name: a silver shield crossed by four blue waves for the region's four rivers (Basento, Sinni, Bradano and Agri), a sea-blue banner with gold lettering, and the Italian tricolor ribbon. The family emblem shown on this site is a modern design made for it in 2026, not historical heraldry.
Confirmed (regional statute of 22 June 1973 and regional graphic guidelines)
What the name means
The Dictionary of American Family Names (Oxford, 2nd ed. 2022) gives Martocci as Italian, "from a derivative of Marta or Marte", or possibly from the root Mart- of the Latin name Martinus. The Italian surname site Cognomix derives the related Martoccia from altered forms of the medieval given names Martucius and Martucia. The ending -occio / -occia is a common Italian affectionate or diminutive suffix, so the name most likely began as a nickname-style form of a given name, "little Marto / Martuccio".

Laurenzana: the family homeland
The family of spellings centers on Laurenzana, a hill town in the province of Potenza in Basilicata. Martoccia is the most common surname in Laurenzana and is borne by roughly 278 families in Italy, two thirds of them in Basilicata. Passenger arrivals to the US between 1830 and 1912 point the same way: of 12 Martocci arrivals with a known origin, 9 came from Laurenzana (2 from Ferrandina, 1 from Naples); of 50 Martoccia arrivals, 37 came from Laurenzana; Martoccio arrivals came mostly from nearby Castelmezzano. Martocci itself is almost unknown in Italy today (6 bearers), which suggests it is largely an American spelling of Martoccia that settled around emigration. The family's own tree confirms the town: of the 45 relatives carrying the name in any spelling whose Italian birthplace is recorded, 43 were born in Laurenzana, in records running from the 1720s to the 1890s. Laurenzana is also the most frequent Italian birthplace across the whole tree, shared by 15 family surnames.

One name, many spellings
Records spell the name Martocci, Martoccio, Martocchio, Martoccia and occasionally Martoci; the family's own tree also records Martuch. Italian surnames commonly drift in their final vowel between records (the -i plural form, the -o and -a singular forms), and American clerks, census takers and the family itself settled on different spellings in different places. Today Martocci is concentrated in New York, New Jersey and Pennsylvania; Martocchio in Connecticut, Massachusetts and California; Martoccio in Illinois. This site's matching engine treats all of these spellings as the same surname.
