My grandfather is José Palumbo. We live in Buenos Aires, Argentina. His father was Nicola. He came from Potenza, Italy, by the end of last century. Nicola Palumbo had two brothers. One of them emigrated to Iquique, Chile. The other one, Antonio Palumbo, remained. Their sons studied Law and left Potenza to go to a bigger city. Then everyone lost contact. If you have some information, please let me know. Thank you.
