You usually cannot know your gotra by surname alone
Many surnames are shared across different gotras
Gotra is typically inherited from the paternal line
Ask your father, grandfather, or other elder family members
Check family records, marriage documents, or religious documents
Ask your family priest or temple priest
Review your clan, lineage, or ancestral village traditions
If your family follows a specific community custom, use that tradition to trace it
Some people use surname as a clue, but it is not reliable
The only accurate way is to confirm through family lineage information
