Wassohbon where is it?

We have great grandparents identified as Bohemian in the 1910 Federal Census. The last name is Kunshier, Joseph and wife, Marie Katherine (nee Teller.) Neither Joseph Sr. or his son, Joseph Jr. identify their home village on their Declarations of Intent to become citizens. Of the other two sons born in Bohemia, one does not apply and dies as a young adult, leaving the third son, Charles who gives his place of birth as Wasshobon, Austria on his Declaration of Intent. Could he mean Wasseau, Bohm? We have had no luck finding such a place. Has anyone heard of Wasshobon? Thank you for any help.
