In the book "A long walk to water", the additional members that joined Salva’s group are from Jurchol Tribe.

Explanation:

'A Long Walk to Water' is story which is partially based on true story of Salva Dut. He was a Somalian from the Dinka tribe who wanted to escape the war that had destroyed his land. So, he trekked across his country and entered Ethiopia. Though they had no idea where they were going, had no food to eat but they kept moving. Salva was joined by a neighbouring tribe, Jurchol.

Salva led a group which had around 1,500 “lost boys”. They walked miles for more than 18 months through desert and three countries. Then they reached “Kakuma refugee camp” in North Kenya. Only 1,200 boys could reach Kenya. From here they got a sponsorship to go to U.S. in 1996.
