the wellknown Demel in Vienna - maybe a connection?
Everything began in the year 1786 when confectionary assistant Ludwig Dehne from Wuerttemberg settled in Vienna.: http://www.demel.at/index_flash.htmhttp://www.viennatouristguide.at/Altstadt/Kaffeehaus/Demel/k...http://de.wikipedia.org/wiki/Ludwig_Dehne
ok, the Demel are not related to the former owner Dehne -> As the son of August Dehne pursued a different career as a lawyer, sold the confectionery Dehne 1857 his oldest companions, Christoph Demel, including all privileges. The business was moved to the carbon market, and was continued by his sons Joseph and Charles, since it says "Christoph Demel's Söhne". http://de.wikipedia.org/wiki/August_Dehne_%28Zuckerb%C3%A4ck...http://de.wikipedia.org/wiki/Demelhttp://en.wikipedia.org/wiki/Demel
