Barbareschi's earliest beginnings took place in Montevideo, Uruguay, where he first drew breath. As he grew up, he found himself in Milan, surrounded by the city's vibrant atmosphere, with his father Francesco Saverio Barbareschi, an engineer and entrepreneur with a storied past as a partisan, having fought under the battle name Luca and served in the Passerini brigade in Varese. His mother, Maria Antonietta Hirsch, an economist of Jewish descent, played a significant role in his upbringing.
Throughout his life, Barbareschi has been blessed with multiple unions. His first marriage was to Patrizia Fachini, with whom he shares three beautiful daughters: Eleonora, Angelica, and Beatrice. Later, during the 1990s, he was in a long-term relationship with the talented actress Lucrezia Lante Della Rovere, lasting a remarkable seven years.
Currently, Barbareschi is married to Elena Monorchio, the daughter of the esteemed former state accountant general Andrea. This union has brought him two more children: Maddalena and Francesco Saverio.
