Unlike his father, John Wells Roberts was a soft spoken man. The only surviving son, he was considered the head of the Roberts family and it was to him that his sisters turned when in trouble. He was one of the first members of the Labour Party in Llanelli and a follower of Keir Hardy. An atheist, he did not force his views on his family and believed that Christianity provided the best moral teaching. He sent his sons to Sunday School until he found they were bunking off and spending their afternoons on the beach. He told the Sunday School superintendent in no uncertain terms, that if he couldn't make the lessons interesting enough to keep them there, he would not enforce their attendance. He and his wife loved entertaining and filled the house at Swansea Road Nurseries with family and friends until his death in 1932.
