Francesco Mazzini

 was the brother of Carlo Mazzini and worked in the mining business as well. He was the uncle of Angelo Mazzini, brother of Maria Mazzini and was the uncle of twins Peter Mazzini and Paul Mazzini as well as Joe Mazzini.

He came to Argentia for his brother's funeral but was mostly interested to see whether he had inherited his brother's valuable estate.

He was eventually murdered by his nephew Angelo Mazzini.

He had a poor relationship with both his nephew and his brother Carlo. He claimed that Carlo once sued him over a game of Monopoly and won.

In a potential future timeline that Angelo illegally observed, he was killed in an industrial accident courteous of his sister Maria Mazzini. (AUDIO: Serpent in the Silver Mask)
