Who is Minocher and Daulat Mirza from Swimming Lessons and what is their importance?

In "Condolence Visit," Minocher is a prominent Parsi, Daulat's loving husband who has died ten days ago after a long illness that for a few days loses its agony. Daulat with apprehension looks forward to receiving a string of mourners, having been coached by the veteran widow Najamai. She knows they will poke and pry into her and Minocher's lives and the painful details of his decline and death. Daulat wishes she had a cassette recorder to get down the sordid details of her husband's agony, in order to satisfy the visitors without running through it continually.
