There are two main Jain views about Mahavira’s marriage:

• Śvetāmbara tradition: Mahavira was married to Yaśodharā (Yashoda) and they had a daughter named Priyadarśanā (also called Anojja in some texts).
• Digambarā tradition: Mahavira did not marry and left home to become an ascetic.

So, yes in Śvetāmbara texts the marriage and daughter are part of the narrative; in Digambara texts this is not accepted. You can read more on these different accounts here and here .
