Re:  Samuel Muhlbauer

I think this is the family on the 1940 census:
https://www.familysearch.org/ark:/61903/3:1:3QSQ-G9MY-G326?i=8&personaUrl=%2Fark%3A%2F61903%2F1%3A1%3AK7MM-CCC

Try searching at www.familysearch.org for more census, and other documents.  In 1940 he is listed as Sam.
Surnames are often mispelled on census and other places, so try doing a non-exact surname search.
