From Jain dharma, there is no universal religious prohibition that a Jain boy cannot marry a Maratha girl.

In practice, it depends on:

• Family tradition
• Sect/community customs
• Mutual agreement about Jain values
• Respect for Ahimsa, vegetarian living, and religious practice

If both partners respect each other’s faith and the Jain boy wants to continue Jain discipline and values, the marriage is generally a social/family matter, not a strict Jain scriptural ban.

In short: Yes, it can happen, but acceptance may vary by family and community.
