Family name origins & meanings
- Italian : from pietra ‘stone’, ‘rock’, with the definite article la (Latin petra, from Greek); probably a topographic name for someone who lived by a prominent rock or on stony ground, or perhaps a metonymic occupational name for a quarryman or stone carver.
- Italian : from feminine form of Pietro, the feminine form probably being due to the influence of the Italian word famiglia ‘family’.
