Birds of a feather fly together so our first ancestors married within same region, religion [few exceptions] for sure one common language to communicate in common tradition to observe.
I would take the spelling BOGUR to be incorrectly written by an office clerk on your grandparent's marriage application. I would suggest locating their church marriage record and even a first child's church baptismal record to confirm your Louis [what was his name in " old country} SPIRKO. You should fing the correct surname by going thru Kurima's and Kurov's church records.
HOVISH seems to me like an americanized surname being that as such it will not be found in Slovakia.
