“But if there are no sons, the sapiṇḍas; if they are wanting, the sahodakas,[7] and those who may be the mother’s sapiṇḍas and those who may be the mother’s sahodakas, should duly perform this ceremony for a man who has no son, and for one who has begotten only a daughter. The daughters and their children should in this way perform the ceremony for the maternal grandfather. But those who are designated as the sons of two such persons should worship their maternal and paternal grandfathers fittingly with the occasional śrāddhas.
