it's been some years since you updated this thread.
I have a Viola Hafernik in my lineage if my findings are correct. my mothers Maiden name is Vrazel, her parents Willie Rudolf Vrazel (1910-1971) and Cecilia Annie Zbranek (1917-1993). WRVrazel's parents were a Joseph Vrazel and Mary Klimek, it is Joseph's father also Joseph that married a Viola Hafernik. Again this is all if my findings are right. i would love some of your input.
