This is really weired because i have a very big family with lots of muffolettos. It is amazing that there are more. But from what I here the muffolettos you are looking for we dont have. We might be related some how but its hard to find out from my perspective.
Let me tell you a little about my background. Im 15 years old. My father comes Perlemo Sicily. He is one of seven children. Five brothers and 2 sitsers. It tragic that both of my gradparents have passed away, but my grandmother sister is still alive. My dads mothers name is Rosa Muffoletto, his fathers name is Vincenzo Muffoletto. He had 2 brothers, so what im thinking is that if we are related it had to be through my grandfathers brothers, because there are no other gaps i can find in our family besides that.
Im very excited about this whole thing and i hope we are related some how.
