I think I might have found a little information on your great grandfather, Frank Palcich. I found it in the Social Security Death Index. This Frank Palcich was born 11 Jul 1877, and died Jul 1965 (you mentioned that your great grandfather died in 1965). He obtained his social security card in the State of Ohio, and his last residence is listed as Europe. This certainly sounds like it could be your Frank Palcich.
