You cannot reliably determine gotra from surname alone
Gotra is usually inherited through the paternal line
Ask your father, grandfather, or other elder family members
Check family records, विवाह पत्रिका, or community documents
Consult your family priest or temple priest
Ask members of your caste or community association
Review ancestral village or clan records if available
Use surname only as a clue, not as proof
Confirm the gotra with multiple family sources before using it
