no i could not really find anything about her.
but maybe you ask Hans Pawlik jr. of the carinthian nobility site if he has info about her. this question must be free and if he knows about her he makes an offer so you can see what it would cost and if you would like to pay for this: http://www.genealogy.at/english/kontakt_eng.htm
otherwise make attempt at the heraldic-society EAGLE in Vienna. i have no idea if they can give answer about her: http://www.adler-wien.at/wDeutsch/index.shtml
