Can you describe the group of devotees from Madras mentioned at the beginning of Chapter 29?

As detailed in Chapter 29, a group of devotees from the Madras region, now known as Chennai, came to Shirdi for Sai Baba's darshan. This group of travelers had spent the year engaged in devotional singing and were on a pilgrimage to Kashi, stopping at Shirdi along the way. The text specifically mentions a family unit within this larger context: a man accompanied by three women—his mother-in-law, wife, and daughter. This particular family followed the tradition of the Ramdasi sect and performed their devotional singing with great enthusiasm. Pleased with their devotion, Baba gave them eight rupees and eight annas.
