Hi ARthur, If you've found the information, please ignore my post.
If not, have you found where and when Norman was born? With a common surname, you must have this info to be sure you've found the correct person. I can look up his name in the California Death Index and Social Secuirty Death INdex.
You might have to be gack to his parents. Do you know where and when they were born? Then I can look through the Censuses and data bases. Then if need be, you can request copies of their obituaries which will provide you more info on where Norman was.
