Luigi/Luis Pellegrinelli and Domenica/Dominga Buzzetti emigrated from Dazio, Italy to Entre Rios in the 1880's. Luigi worked as a coal miner. They had three sons that I know of while in Argentina, Donato Oreste (1885), Jose Victorio Enrique (1886), and Luis Geronimo Cesar (1888). At some point Domenica returned to Dazio. Donato Oreste and Jose emigrated to America in the early 1900's. What happened to Luis the father and Luis Cesar? They also had a daughter Pierina (1878) who was born and later married in Dazio. Did Pierina emigrate to Argentina too?
