Hi Cristian! Yes, we may be related.First off, you speak much better Englidh than I can ever hope to speak in Spanish I think the word you were looking for is siblings (means brothers and sisters).Speranza Tedesco was my grandmother, she married Dominic Tamburino.The names of her brothers that I have are Antonio, Gennero, Giovanni, Guiseppe, Salvatore and Armondo (the youngest I believe).Sisters were Irma, Luigina (who still lives in Italy) and my grandmother.I understand that there maybe more siblings. Juan is a new name for me (do you have a date and place of birth etc. for him?) but I do know that there is a branch of the family in Argentina.I vaquely remember meeting some of them when I was a very little girl.
Anything you have on the family would be greatly appreciated and if you have questions I can answer regarding my own research I will be happy to answer.
