I don't know why, but something prompts me to write this note. I have no information on your family name, but the very fact I have found someone who has ancesters in Sulmona, I take the liberty to write.
Years ago I had someone write to the church, St. Panfilio, and received information as well as from the Comune.
My great grandparents were Vincenzo Alicandri and Leonilda Procacini. Grandparents Andrea Gentile (from Antrodoco) and Concetta Alicandri.
I hope to visit the house where my father was born. The street is there, now an alley, I hope the house is also. Good luck on you search,
