Can you tell me about 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 to Shirdi for Sai Baba's darshan. These devotees, who belonged to the Ramdasi sect, were on a pilgrimage to Kashi and stopped at Shirdi along the way, having heard of Baba's fame. The group consisted of four people: a man with his mother-in-law, wife, and daughter. They stayed in Shirdi for several days, performing loving and enthusiastic devotional singing. The text notes that Baba was pleased with them and gave them eight rupees and eight annas, demonstrating his generous and compassionate nature towards pilgrims.
