From Ancestry.com, there is a picture of the Feiller family crest (from Hungary). Note that from the current location of Poppendorf today in Austria, that in the timeframe she was born, it was likely in Hungary (within the larger Austro-Hungarian empire).
Text on the crest:
Ich brach Sie mir unter Truemmern.
From the written entry about the crest:
Ungar. Indigenat d.d. 1840 - Gesetz Art 48 - fuer Franz Xav. Feiller, in Ansehung erworbener Verdienste, gelegentlich der Ueberschewemming im J. 1838 in Pesth. (L.R. sub Nr. 15726).
Perhaps someone on this list whose German is better than mine can give you a transalation of the above.
