I am a Rosch, without the "umlaut" or "e". So would we be included? My research has narrowed down to Schoenecken, Germany, where my contacts say there are different lines of Rosch and the ones with the umlaut/e are of another line.

I guess the DNA can tell us. I accessed your website but some of the features didn't work, so I'm not clear about the nature of your project. Please send any info to fdrosch@yahoo.com.
