Dobhada is not a widely documented Jain surname in standard Jain texts. In Jain communities, surnames (family names) often reflect regional origins, community subgroups, or gotra, and practices can vary by region (Digambar vs. Shwetambar) and by local lineage.

If you are tracing a specific family, the most reliable sources are:

• speaking with elders in the family or local Jain community
• records kept by local derasars/temples or community organizations in your region

Would you like me to explain how Jain gotras and regional naming patterns typically work, or help you search for more specific references on JainKnowledge?
