G'day Daniel, I am the David Morello to whom my uncle Anthony makes mention of, please contact me via e mail at david_morello@yahoo.com.au so we can discuss our most likely bloodties etc which is my beliefs from what you have previously written . I also have a group on facebook called Morello which is basicly dedicated to the name and family research, it now has many members, please feel free to have a look and also become a member, you may find some interesting things in my findings there if you search it, but please contact me on the e mail.
Regards David.
