Can you tell me about the group of devotees from Madras who visited Sai Baba?

Chapter 29 describes a group of devotees from the Madras region (now Chennai) who came to Shirdi for Sai Baba's darshan. They were on a pilgrimage to Kashi and stopped at Shirdi along the way, having heard of Baba's fame. This group, which consisted of one man and three women (a mother-in-law, wife, and daughter), followed the tradition of the Ramdasi sect. The text mentions that they performed devotional singing with great enthusiasm. After staying near Sai for several days and attaining peace, Baba, pleased with them, gave them a gift of eight rupees and eight annas.
