Grandmother's marriage certificate

Hello all,

I am unable to find my grandmother's marriage certificate as I am not exactly sure where my grandparents were married. All I really know is that they married sometime after ww2 in Europe. She is the ancestor I am trying to get Slovak CBD through.

I have her naturalization records and her SS-5 that both contain her maiden name with her married last name. Is that enough?

Also, in the US she put an english translation of her name (Viola) on all of her documents and that was her legal first name here. On her Rodny List as well as the 1930 census copy I have (both came from slovak archives) her first name was Ibolya. Will this be an issue at all?

Thanks all for the help!
