I have follow Willium Ironside from Scotland to Rapid City Manatoba. He had 2 children with my Grandmother last one in 1906. There was no marrage in this union. After the birth of second child William disappeared and I can not find also his brother could not find. I think he ended up in a Hospital in canada with severe mental disorders. I do not know how to research such hospitals. Is there anyone that knows how to do so? I would love some help. Thank You
