There is a town with name Scherweiler, today Scherwiller: http://atlas.mapquest.com/maps/map.adp?zoom=5&latlongtyp... Elasass-Lothringen belonged to France before 1870, and to the German Empire from 1871-1918: After the Franco-Prussian War of 1870, the area was annexed by the newly-created German Empire in 1871 by the Treaty of Frankfurt and became a Reichsland (see: http://en.wikipedia.org/wiki/Alsace-Lorraine ) Only in 1919 Elsass-Lothringen was independent - now it is France.
This could be why on one census she lists Alsace-Lorraine and on another she lists Germany.
