Can you describe the roles and contributions of Mhalasapati, Kashiram Shimpi, and Appa Jagle as early devotees of Sai Baba?

The introduction in Chapter 0 highlights the importance of three early devotees. Mhalasapati was the first to call Maharaj "Sai Baba" and introduced him to the village. He, along with Kashiram Shimpi and Appa Jagle, had a custom of serving saints who came to Shirdi. All three became devoted to Baba. Kashiram's service was particularly notable; he served with body, mind, and wealth, stitching a green kafni for Baba and taking a vow to provide him with chillum, tobacco, firewood, and money. The text notes that both Kashiram and Appa were fortunate to pass away on an Ekadashi day.
