Hello, I am trying to trace back my great grandfather's heritage. His surname is listed online as Mike Brenzo along with some signatures I found from WWI and WWII and on his wife's (Mary Onyock) death certificate. His birthdate appears to be March 15, 1881 with a birth place of Sariska, Austria, immigrating to Marblehead, Ohio around 1898 and Slovak is listed as his language. I have searched on many websites for Brenzo and it's just not showing up. Any chance his given surname was somthing like Brenzova, Brenzovich, Brenza (my grandma Dora, his daughter, had it as Brenza)Brendza, etc.? Any advice on finding out more about his surname? I would appreciate anything you can offer!
