In Jain community usage, “Bhandia” and “Bhansali” are not traditionally treated as the same gotra.

They may both be Jain surnames (often among Shwetambar Jains, especially Gujarati/Marwari), but:

• Gotra / kul is usually based on a specific accepted lineage name.
• “Bhansali” is a well‑known Jain surname/group.
• “Bhandia” is different in pronunciation and lineage and is generally counted separately where traditional records are followed.

However, in many places people mix up surname, sangh, caste, and gotra, so families themselves sometimes keep their own traditional understanding. For correct religious purposes (like marriage within/beyond gotra), families usually follow their own elder’s / community’s record.

So, in simple terms: No, Bhandia and Bhansali are not the same gotra in standard Jain community understanding, even if they sound somewhat similar.
