Sorry I don't speak spanish only italian and english. About Tedesco' tree I know a lot of Tedesco in North Italy, I have a very old family tree, the oldest Tedesco was Tedesco Bastian 1515 and so on. I have some relatives in Argentina in Rosario SantaFe, because the brother (Giacomo Tedesco born 1857 in Italy)of my greatgrandfather Agostino Tedesco Lugari(1859)from S.Zenone degli Ezzelini (Treviso) lived in Rosario.(Guerrino Tedesco son of Giuseppe 1888 son of Antonio 1851 maybe lived in Mar della Plata). If you need more information about Tedesco in Italy please write me.
