Searching for Elschner from Taura Sitzenrode and More IN Germany

Seeking family connections for Hans Frederick Wilhelm Elschner and Hildegard Kloenne, of Ludwigsruh, Germany (before WWII, now Gorzow area Poland).
Interested in discovering history of family crest. So far no luck.
Have many document copies, many posted at my website at www.cagleonline.com
