Tommasina Gonzaga

Tommasina Gonzaga was a Mantuan noblewoman, the daughter of Luigi I Gonzaga, Mantua's first capitano del popolo, and Richilda Ramberti. In 1319 she married Guglielmo Azzone Castelbarco, a condottiero serving the della Scala of Verona, who in 1328 led Veronese troops that helped expel the Bonacolsi from Mantua and bring the Gonzaga to power.

In 1333 the couple hosted Charles IV of Luxembourg, the future emperor, at their castle of Avio. She died in 1372, leaving six children.
