Correction, Grazia was born in 1907, so would have been five, close to six, when left in Furnari in 1913.

I just wrote a long response, and it does not show as having posted, so I have to make this quicker.

I was just in Fùrnari. I believe Crisafulli is the most common surname there.

My grandfather's mother's second husband had the last name Crisafulli, but I don't think they're connected to yours ...
