Italian wedding?

I am pretty sure this picture was taken in Italy. My grandparents had 3 different portraits of this this couple, including one later with a little boy. Since they had 3 portraits of these people, I assume they were family, and THINKING maybe still in Italy. Why else would my grandparents have so many pictures of them? The surnames would be Iacobucci or Marchetti from San Valentino...or DiFrancesco or DiSantis from Alanno; both Pescara, Abruzzo, Italy. Both my gr-grandmother and gr-grandfather, Rosaria DiFrancesco (1890-1963) and Vito Iacobucci (1888-1951) had brothers/sisters who stayed in Italy. Any help would be greatly appreciated!!

I would like to know who any and/or all of these people are. I think the bride, the bridesmaid and the man standing all have the same nose, but I really have no clue who they are, except that they are probably from Alanno, Italy or San Valntino, Pescara, Abruzzo, Italy.
