I found a WWI draft registration record for a Georg Sajko in Milwaukee, Wisconsin. The record indicates he had been from Marsburg, Austria, Slovenia.
This is a locality associated with my grandmother, Julianna (Julia) Sajko. From what I can piece together so far, she was born in Stanovsko, Brezovica, Slovenia, lived in Marburg an der Drau, Slovenia, and worked in Modling, Niederösterreich, Austria, prior to emigrating to the United States.
If you have any information on the Slovenian Sajko family who would have been connected to these locations, please contact me.
