Can I perform Shradh in Gaya for multiple deceased family members in a single ceremony?

Yes. A single Gaya Shradh ceremony covers all your ancestors as a collective — including parents, grandparents, great-grandparents, and ancestors going back seven generations on both the paternal and maternal sides, according to the Garuda Purana. Additional offerings can be made individually for specific family members whose names you wish to state separately. Your pandit will structure the Sankalpa to include all the ancestors you wish to benefit.
