prayas

Hi I am Prayas Bhatia, from Chandigarh. I was born in delhi. My great grandparents came from sialkot in pakistan now, after partition. My gotra is Gautam. I want to know about my Kuldevta and Kuldevi. I asked my old family members ...but no one has exact information or place where they are located, Is there any way to find out about my kuldevi/kuldevta, Regards Prayas
