Jain traditions differ on Mahavira’s family:

• Svetambara tradition: Mahavira had a wife named Yashoda (Yaśodā) and a daughter named Priyadarṣhaṇa (also called Anojja). Priyadarśhaṇa was married to Jamali. This is the common portrayal in Svetambara texts. You can read more here

• Digambara tradition: Mahavira is considered to have remained a bachelor and did not have a wife or children. This is the Digambara stance.

If you’d like, I can summarize the main points from the key Jain texts that discuss these differences.
