Volumnia Capulet

Volumnia Capulet is Tybalt Volumnia De Capulet's mother and Leontes van de Montague's first lover.

History
Most of Volumnia's life unknown but she belongs to the Capulets house. At some point, Leontes meet Volumnia and a bond of love grew between them. Unfortunately, Leontes left her who would gave birth to Tybalt Volumnia De Capulet in favor of marrying Portia Clemenzia de Ebe.

It is unknown what happened to Volumnia after Leontes left her. Since Volumnia didn't appear in the series, Volumnia presumably died in a unknown circumstance at some point after Leontes left her or during the massacre of The Capulets.

In episode 22, there is a small flashback of a young Lord Montague (assumingly) meeting Tybalt's mother.

Volumnia's relationship with her son, Tybalt is unknown but is it possible that Tybalt cares for her and promise to take revenge on his own father , Leontes.
