Could you describe the roles of Nanasaheb Nimonkar and Damu Shet Kasar in the annual Ram Navami festival?

The Ram Navami festival featured a grand procession where two large ceremonial flags were carried to the Masjid. According to Chapter 0, these two flags were contributed by two prominent devotees. The first flag came from Ra. Shankarrao Raghunath Deshpande, who was also known as Nanasaheb Nimonkar. The second flag was provided by Damu Shet Kasar of Ahmednagar. Damu Shet's contribution was part of a vow he took out of gratitude for the birth of his son, a vow which also included feeding the Fakirs on Ram Navami day.
