Can you describe the group of devotees from Madras mentioned in the text?

Chapter 29 describes a group of devotees from the Madras region (now Chennai) who came for Sai Baba's darshan. This group of four travelers, consisting of a man with his mother-in-law, wife, and daughter, were on a pilgrimage to Kashi and stopped at Shirdi. They were followers of the Ramdasi sect and had spent the previous year engaged in devotional singing. After taking darshan of Sai, they attained peace and stayed for several days, performing their devotional singing with great enthusiasm. Baba, pleased with them, gave them eight rupees and eight annas.
