Here is the info I received:
"My father in law Isidoro DiBiase is an Italian immigrant (from the early 50’s). On one of his return trips from visiting his family in the Abruzzi he brought back a cutting of his personal childhood favorite fig from his hometown of Raiano north-west of Rome. The fig was spelled differently but named about the same, (corraggio). I think it actually means something like “strong heart”. When we built our house here in NC he brought me a cutting which has been growing here since. Oddly, the fig fruit actually grows with a crease that makes the fruit look heart-shaped. I can only assume it was named after the shape of its fruit."
