Did this Alphonse have a brother or cousin named Bartolomeo (Bartholemew)? The De Stefanos I know are from Anzano di Puglia (about 5km from Rochetta), and may very well be realktesd to you. My grandfather was Michele De Stefano, and my mother is AngiolinaDe Stefano. Michele died in 1974ish, he was married to Maddalena Auciello. These are my grandparents on my mother's aside (we still have thier house in Anzano). Many Anzanesi dispersed throughout the world, so I'm also interested in knowing who you all are!
