Dear Ms. Gabusi,
Thank you for posting your request on History Hub!
We suggest that you review Archives of Hungary; Hungary Online Genealogy Records Genealogy; and Hungary Genealogy & Hungary Family History Resources websites to assist you to determine where Alexander Demjanovich and his parents were born. Please see our previous response to your earlier request Seeking records for Alexander Demjanovich & Edward Demjanovich.
With regard to Resov, you may wish to search Czech Republic Archives and Libraries Genealogy; Digital archives; List of archives in the Czech Republic; and Czech Archives on Internet websites for other available resources.
We hope this is helpful. Best of luck with your family research!
I found this for Alexander on familysearch.org. The birth date is off by a few days based on death info (below).
1915 census which lists his wife. It continues on the nbext page with his other children.
Can't find Edward.
I hope this helps.
