Long-lived and short-lived families.

The first attempt at this ran into an obvious trap: family lines with a lot of descendants who emigrated to Chicago looked dramatically longer-lived than everyone else — the "Rich" line (the Chicago-Americanized branch of Riccio) topped the list at a 73-year average, well clear of anyone else. But that's not a family trait. Most of that line lived their adult lives in 20th-century America with modern medicine and sanitation, not 18th- or 19th-century Sassano. Comparing that fairly against families who stayed in Italy for centuries isn't measuring genetics — it's measuring which families happened to catch a later, healthier era.

So the numbers below exclude anyone with a Chicago or Illinois connection entirely, comparing only people who lived and died in and around Sassano itself, and only counting adults — deaths at 15 or older, since infant and child mortality reflects a different set of causes than adult longevity does. Only surnames with at least 20 qualifying adult deaths are included, so a family of three isn't skewing the picture.

Against a baseline adult average of 59.6 years (median 63), the longest-lived line remains Miele at a 72.4-year average, backed by 30 qualifying adults. Delisa, Martucci, and Stavola round out the rest of the top five, with di Stefano now tied with Stavola at 65.7. The shortest-lived is still Battista, though its average ticked up slightly to 50.6 years as more records came in; Gruccio, Baialardo, di Lorenzo, and Orlando follow close behind. The gap between the top and bottom of the list has narrowed a bit from the last update, from just over 23 years to just under 22 — a reminder that these rankings, especially near the bottom, can still move as the tree grows.
