You might find information in the research facilitiy of the Waukesha Historical Society. I do know that they have records of interred mental ill patients and other such records. So, I assume they will have the Industrial School for Boys Records as well. I believe this school or jail as it is now referred to is located in Wales and is still in operation and filled to capacity. Because these children are minors--you will most likely have to sign some waver and show proof that the person you are looking up is deceased. Your father could obtain the records himself if he is still alive.
