Yes, Salce is from Fornelli in northwest Molise and a very tasty fig.
Abruzzo and Molise were formerly treated as one region (Abruzzo e Molise). Back in the late 60s or early 70s, they were separated. L'Aquila, where that terrible earthquake happened a few years ago, is the capital of Abruzzo. Campobasso is the capital of Molise.
Aaron, I am still interested in learning more about your two unknowns. Do you have more information narrowing down where in Abruzzo these figs originated, or a way to get it?
Mario, That sounds enticing. I have mentioned on this forum that my grandfather came from San Pietro Avellana, just east of Castel di Sangro, but across the border in Molise.
