Answer

In traditional Digambara Jain marriage matchmaking, three kuls are generally avoided:

• Father’s kul
• Mother’s kul
• Grandmother’s kul

Explanation

A marriage match is traditionally avoided within these close family lineages to prevent marrying within near ancestral relations. This is connected with maintaining proper family boundaries and avoiding close-blood relationships.

Takeaway

So, in Digambara Jain matchmaking, the commonly avoided number is 3 kuls.
