Yes, DJ Pauly D, whose real name is Paul DelVecchio, is of Italian descent. He was born in Providence, Rhode Island, and embraces his Italian heritage.
Some Italian last names starting with "D" are Di Giovanni, De Luca, De Rossi, and D'Angelo.
Pauly gives no indication to any Portuguese ancestry so my guess is 'no, he is full-on Italian.
The Spanish name "Vincenzo" means "Victorious" and, "Conquer"
There are 21 letters in the Italian alphabet they are A, B, C, D, E, F, G, H, I, L, M, N, O, P, Q, R, S, T, U, V, and Z.
