Well, without more context, it's difficult to tell the exact 'first brides grave story'. However, generally speaking, such a story could involve a young bride who was the first in a long line of brides in a particular area or family. She might have faced hardships like illness or some sort of accident that led to her death. Her grave could then be a focal point for the community's superstitions or a place where people would come to pay respects and also to remember the history of the area's marital traditions. For example, if she was part of a pioneer family, her story could be intertwined with the founding of the community and the development of marriage customs there.
The 'Brides for Indians Program' had a real story full of various aspects. In some cases, it was an attempt to solve the problem of unmarried men in India. The program often involved matchmaking across different regions. But the real story also includes the hardships of the brides. They were suddenly thrust into a new world. They had to deal with new diets, different religious practices, and sometimes, a lack of support from their new families. Moreover, the economic aspect also played a role. Some families might have seen these brides as a way to get more labor or financial support, which added to the problems faced by the brides.
