The 35th edition of the Carnival of Genealogy has been posted. The Genetic Genealogist has addressed the mysteries submitted by 19 bloggers, plus addressing some ethical concerns raised in two submissions.

That won't help me figure out who her parents were, or help me get into Native American societies, but it would be another origin to add to my melting pot. Proving relationships with surviving "Dudelsacks" isn't a job for DNA since I believe the Y chromosome from the one other male line I know about doesn't survive today. There's always a chance I will find descendants of siblings that remained in Europe.
