Pat it is always a pleasure to talk with someone who is interested in the failla name
I will try to help you with your search. for starters the Failla name is common in the palermo county area but most of the faillas roots in this area come from the same line. I say most since the word failla originaly comes from the naples area of Italy.. the meaning is a kind of popular beach tree in that area.
