Student Profile: B. Jachimowicz

So I found some interesting information at this stage. But it brings me back to the begining to where Benjamin is not his name. I am leaning towards Binem Jachimowicz. But back to the names of Beniamin, there is one on the survivor data base. However, while conducting a ton of research, I have found more on Binem who changed his name to Ben James which links to Benjamin. Im not sure where to go from here. Can you please guide me in the right direction?
