How can you tell the difference between a northern and southern italian easily?

[Mens-Sarda]

Enrico Letta looks surely more Central than Southern.

Her mother surname is Banchi (and not Bianchi,) according to many sources she was born in Sassari and raised in Porto Torres, Sardinia, and she moved to Tuscany for studying reasons. You're right, Banchi is a Tuscan surname, so basically she could be Sardinian of Tuscan ancestry.

Letta's mother


While Letta's father is from Avezzano, Abruzzo. Here a pic of his uncle, Gianni Letta, famous and influent Italian politician born in Abruzzo.

Enrico Letta's mother is only half Sardinian, Banchi is not a Sardinian surname, she's the daughter of an Italian soldier from Tuscany stationed here during WW2 and of a Sardinian woman from Porto Torres

Thanks. I found that she could have some Tuscan ancestry by his paternal line but I didn't find any info about her.
