You are searching in all the wrong places! You need to post your messsage to the Slovenia board
Look at the 1930 census... he and Mary were Slovenian. Also you said he was running from a war.... there was no war in 1911... and besides if his year of arrival on the 1930 census is correct.... then he would have been around 17 years old... draft was 21 in the old Austro-Hungarian Empire. You mentioned that you thought he changed his name to avoid that war.... but in fact he would have had to recieve permission to leave Austria-Hungary and would have had to have supporting documents. If he in fact came to the US under another name he more likely used someone elses passport.
Also Louis is not a name you would find in Slovenia.... BUT Alojsia is a name found there and many men with this name changed their name to Louis in America.
Here the closest match found in immigration records

Estimated birth year: abt 1891
Port of Departure: Havre
Ship Name: La Provence
Microfilm Serial: T715
Microfilm Roll: T715_1619
Birth Location: Austria
Birth Location Other: dolj. radula
Destination to brother in law Martin JORDAN at Greensburg PA
Although he was going to Pennsylvania there is a notation that was made in 1939 when he applied for US Citizenship at Salt Lake City, UT!
Now for Mary's arrival if you were paying attention you will notice she lists Alois not Louis as her bridegroom. Also notice that she lists her next of kin in Slovenia as an Uncle... which would indicate her parents had passed away.
Her birthplace is listed as Radolje... and Alojs manifest lists his as Dolj. Radola.... which i believe to be the same place.... however from what I see this place does not exist anymore but is located in the Municipality of SEVNICA
You need to post to the Slovenia board, where there are some people who know the villages in that country.
Oh and Yugoslavia did not exist until after the end of WW I, 1918. So while they came from the same place the entity that ruled Slovenia changed.
