Nancy, without the census' it will be difficult.I found my great aunt through a census. She was listed as a boarder in what seems like a group home in San Jose.I can't find that group home or the owner's name anywhere. Can you go to a city or county directory for those years and look for names. Then it is a matter of trying to find who bought the insane asylum and try to get that organization to tell you anything.It gets incredibly dicey, imo.Perhaps someone can really come up with a good hint. Good luck.
