My 2nd great-grandparents, Julius and Elizabeth (Renick/Renyák) Ballas are buried in Windber, Someset Co., PA. My problem is that no one knows (or tells me) the name of the cemetery, and I'm sure there's more than one. It's even more difficult because I do not know when they were born or when they died (my guess is that they died in the 1960s-1970s).
What I do know is that Elizabeth was Slovak, so I'm thinking that maybe they could be buried in St. John's Slovak Roman Catholic Cemetery. But I don't even know the address or phone number for that cemetery.
My questions are:
What are the names of the cemeteries that are in Windber, PA? And (if possible) when I can find the addresses and phone numbers for these places?
I would greatly appreciate all of your help.

Thank you for your time.
Regards,
Meghan
