Oh wow, Eddie, thanks so much! Elizabeth Jones is CW's mother, but also his wife, so it could be either. Walter Piggott is Elizabeth's(mother) brother-in-law, married to her sister Kate, nee' Goodenough.
21 Carlton street is the address given by Albert Harry Jones on his WW1 records for his mother:)
This means that CW Jones and his wife ES Jones must have left their children at either of these addresses when they went to South Africa.
