Faillaci is the correct spelling according to my Sicilian relatives. I have found several cousins in the Philadelphia area, two came from Caronia Sicily, which is where my grandfather is from. I plan to go to Sicily next year to do some extensive research, but for now my next venture is to try the Mormon database for more information. If I come across any info regarding your grandfather, I will pass it on. Also, if you find out anything, please contact me. Good luck on your search.
