The Name
What the surnames in this archive mean, roughly how common they are, and — the useful part — how much that tells you about whether two people who share one are related.
Mazza
Mazza is the Italian for a club, a mace or a mallet, from the Latin mattea. As a surname it was coined in all the usual ways at once: as a nickname for a strong or a violent man, as a trade name for someone who worked with a mallet or a maul, and — most often — from the medieval personal name Mazzo, itself a short form of names like Giacomazzo and Tommazzo.
It is one of the most widespread surnames in Italy, found from Lombardy to Sicily, and it was coined independently many times over. There is no founding Mazza family. Two Mazza households in the same Sicilian town are much more likely to be related than two Mazza in different provinces — but "much more likely" is a probability, and this archive does not publish probabilities as descents. That is precisely the situation at Piedimonte Etneo, where 118 Mazza sit in two groups that no record joins.
The others
| Name | Here | Where it belongs | What it is |
|---|---|---|---|
| Prostamo | 84 | Briatico, Vibo Valentia | Rare, and concentrated. Almost the whole Italian distribution sits in a few Calabrian comuni around Vibo Valentia. A rare surname in one small place is the best gift a genealogist gets: two Prostamo of Briatico almost certainly are related. |
| Polistena | 45 | Scilla, Reggio Calabria | A toponymic — from the town of Polistena in the province of Reggio Calabria. It marks a family that moved from there, and was named for having done so. |
| Arena | 39 | Scilla, Reggio Calabria | Very common across Calabria and Sicily; from arena, sand — a place-name element. Common enough that a shared Arena surname is worth nothing on its own. The archive holds four undated Giuseppe Arena and keeps them apart. |
| Nicotra | 8 | Piedimonte Etneo, Catania | Strongly eastern Sicilian, and heavily concentrated around Catania — which is exactly where this archive finds it. |
| Melluso | 12 | Briatico | Southern, both Sicilian and Calabrian; probably from mele, honey, or a diminutive of a personal name. |
| Anile | 12 | Briatico / Potenzoni | Calabrian and uncommon, clustered in the Vibo Valentia area. |
| Donato | 20 | Scilla | From the personal name Donato — "given". Common everywhere in the south. |
| Cavallaro | 13 | Scilla / Brisbane | A trade name: a horseman, a groom, a keeper of horses. |
| Bova | 13 | Reggio Calabria | Another toponymic — Bova is a Greek-speaking comune in the far south of Calabria. |
Why this page exists
Because the single commonest error in family history is treating a surname as a family. It is not one. It is a label that was attached, independently, to unrelated people, in different centuries, for different reasons — and then inherited. The useful question is never "are they both Mazza?" It is "how rare is the name, and how small is the place?" By that measure the strongest evidence in this archive belongs not to Mazza at all but to Prostamo of Briatico: a rare name in one comune, eight generations deep.
