Language (German) most important.
Dorothea is a German female given name found in "German Names from Rottweil, Baden-Württemberg, 1441" by Aryanhwy merch Catmael (http://www.ellipsis.cx/~liana/names/german/rottweil1441.html).
SENA Appendix A states that German names may take a locative byname marked by "von -place-."
Ulm is a city in the Baden-Wurttemberg area of Germany. It's name is attested to 654, where it is called Hulma, in a document signed by King Louis the German. In Georg Braun and franz Hogenberg's "Civitates Orbis Terrarum" (Cologne, 1572), the woodcut map of Ulm is labeled both in Latin as "Ulma" and in German as "Ulm".

Correction to Device (2019-Sep-16 16:09:11): Feather and Quill Pen are similar in appearance and I do not think have a default position.
So this may need to be blazoned as "Per pales gules and sable, a feather palewise and in chief two crescents argent."
Having changed half of the primary charge and adding secondary charges, this is clear of Lachlann Alexander MacCoag (July 2015) Per pale gules and sable, in saltire a feather and a key argent.
