Jan Victor Bober.
As Dominic has said, you would need to know if that name is spelt correctly. His surname might well indeed be Bober, but the surname originally comes from Polish Bóbr ( Beaver ) as mentioned above. It could also have been shortened from Boberski for example. Jan would be Janusz, and Victor, Wiktor.
Without further information it's a bit like looking for a needle in a haystack I'm afraid.
