Where the Giamboi surname comes from
Giamboi carries within it the most common name in Sicily: Giovanni. In the speech of the towns, Giovanni was shaped into many short, familiar forms. One of them, Giambò, probably gave rise first to a family nickname and then to the surname. It is the explanation most scholars follow, but it remains a theory.
