I want to thank Logan for this post.  I accessed it (there is an option to use it in English) and searched for my family name Furstenberg (with an umlaut).  Nothing under Fur, but when I looked under Fuer..., I found a card(front and back) that I believe is my family.  It's difficult to read, but the names are correct.  When I have more time, I'm going to have to see what I can figure out.  So if you don't find your name under your first spelling attempt, don't give up!

Best,
