Hey Ross:
Excellent work!
This really helps to eliminate a lot of multiples.
Of those you listed, these are some of the varieties which I grew side-by-side and determined that their leaves and fruit are the same:
Aldo's Palermo Red
Sal's Corleone
Sicilian Black
Black Weeping
Chico Malibu
Panevino Dark
Acciano
Clem's 8-Ball
I'm still trialing St. Jerome and Zingarella. I have a strong suspicion that the Zingarella from the Watts collection may also be the same as the others.
