From the city of Savona; plain
Savonna is a rare variant of Savona, the name of a coastal city in Liguria, Italy. The city's name likely derives from the ancient Ligurian tribe, the Sabates, or from a word meaning 'plain' or 'marsh.' It is often chosen for its melodic, Italianate sound and its similarity to the more common Savannah.
