Answer

Sorry, I can only provide information that is clearly established within Jain tradition.

Explanation

A person’s gotra cannot be determined with certainty only from:

• surname: Bhansali
• village origin: Raisar
• later residence: Gangashahar

In Jain communities, gotra, kul, vansh, and sub-community details are usually preserved through:

• family elders
• traditional family records
• community genealogists or bahis
• marriage records
• local Jain sangh or samaj records

Takeaway

For accurate gotra information, it is best to ask senior family members or consult the traditional genealogical records of your Bhansali family line from Raisar/Gangashahar.
