In 'The Merchant of Venice', Shylock's daughter who elopes with Lorenzo is Jessica.
Jessica appears in Act 2 as the daughter of Shylock, a Jewish moneylender in Venice. Unhappy in her father's household, which she describes as restrictive and oppressive, she secretly plans to leave with Lorenzo, a Christian gentleman. During a masquerade, she disguises herself as a page and escapes, taking some of Shylock's money and jewels.
The elopement is more than a romantic subplot: it intensifies Shylock's anger and helps drive the action toward Antonio's trial over the famous “pound of flesh” bond. Jessica and Lorenzo later live at Belmont with Portia and Bassanio, and Jessica converts to Christianity. The story is sometimes confused because Portia is the play's central heroine, while Nerissa is Portia's companion and marries Gratiano. Antonio, meanwhile, is the merchant named in the title and has no family connection to Shylock.
