Hmmmm, you might want to try searching with different name spellings, try Rapheal, Raphael, Rapheale, Raephal, etc. There are many possiblilities especily if Mr Bianco was Italian. Also, need to check the 1930 census for Ralph between the age of about 8 to 16.

Dear M1-
I'd nearly forgotten about that present.. I figured if ever anybody could track down a WWII Army Engineer I'd put my money on you! 
Whether or not you can locate any info about him, I am certain that he would be proud to know that his ribbons & books found a place in your home.
Hugs,
