The Satcharitra mentions Damu Anna was childless. Can you explain what happened to him according to the text?

The story of Damu Anna, a well-to-do devotee from Ahmednagar, highlights Sai Baba's grace in fulfilling the desires of his followers. According to Chapter 25, despite having two wives, Damu Anna was without children. However, through the blessings of Sai Baba, he was eventually blessed with sons. This blessing was a direct result of Sai's grace, demonstrating how Sai removes the suffering of his devotees and grants their desired objects once one-pointed faith is established in them.
