You have to trace immigration papers to establish town/village of origin. "Austria" could be today's Austria -- but it could also be Czech Republic, Poland, Slovenia, etc.
STEINBACH is quite a common name in today's Austria.
GLAZER is unusual. Only a few listed in directoryhttp://www.etb.at/
any they're in Lower Austria, near Vienna.
Your GLAZER might however be an English language (phonetic) version of GLASER (very common) or a version of GLATZER (very common too).
