Who was the wealthy Parsi merchant that was deeply troubled by not having a son?

The book describes a famous, religious, and popular Parsi merchant from Nizam's state named Ratanji. According to Chapter 14, he possessed vast wealth, including property, carriages, and farms, and was known for his generosity. However, despite this outward prosperity, he was consumed by an inner worry because he had no son, only twelve daughters. This lack of a male heir to continue his lineage made him feel that his great wealth and happiness were entirely fruitless. His sorrow was so profound that he was constantly uneasy and found no pleasure in food or drink.
