The only item you entered that is for the Ralph Nichols I referred to is the 1940 census. Ralph & Warren both have different birth dates, and Warren is still alive.
I would still like to now the source of this entry you posted:

Rank: Master Sergeant
Combat Organization: United States Merchant Marine
Death Date: 9 Jun 1945
Monument: Rhone, Draguignan, France

Thank you for your help.
