Families: Bumbera, Dzmura, Rohal

I have been very fortunate to find my paternal Bumbera ancestors [Trebisov]and Dzmura cousins [Livov area] through the LDS records and the assistance of a researcher in Kosice, Slovak Republic.
Now I am hoping to find missing U.S. descendants. I would appreciate hearing from relatives and friends of the following families:
Andy & Barbara Bumbera of Braddock, PA; John & Victoria [Baligrocky] Dzmura of Ohio/PA;
Juliana [Dzmura] & Mike Mikita of Ohio with descendants in California;
Bill & Anna Rohal of Ohio & California [may be related to a Dzmura wife.
Thanks, Barbara
