[Ger-Poland-Volhynia] Surname HRYNJKE ?

[gpvjem]

    I received a request for research assistance for the name Boleslaw HRYNJKE.  
The given name of Boleslaw = Wilhelm, but the surname taken from a passport has me confused.  It appears to be  Slovac rather than Polish.  I am inclined to think that it should possibly have been HRYNSKE.
    Any hints or suggestions would be greatly appreciated.
