In Austro-Hungary Jozef could have been a none-Jewish secular name. As Jacob mentioned in his previous comment,
Josef's Hebrew name could have been Ze'ev which is also Wolf and Wilhelm. 
The same could have applied to Lipot- Samuel though I have no explanation to how  Isidor got into here.
Unless his secular name was Isidor, his Hebrew double name Samuel - Yehuda and Lipot could have been the Hungarian version of Yehuda.
