Hi:I found some dates for your great aunt and uncle.I wasn't sure exactly what you were looking for.
Arthur Erbes born February 15, 1884 died Sept 1967 in Hollywood, FL33022
Dorothy Erbes born November 6, 1885 died November 1979 in Hollywood, Fl33022.
You can order a copy of their death certificates for $5.00 from the State of Florida.If you know what cemetery they might be buried in down here I would be more than HAPPY to get pictures for you. If you don't know the death certificate would probably say.I don't know when I would be getting to the library again to find obits for you so it might be quicker to get the death certificates.Let me know if I can try and help out further.Ilive in Hollywood.
