Having recently come upon the maiden name of my ancestor Margaret Robitzer, I've been engaged in discovering her roots in the town of Uttwiller (aka Ottweiler), Alsace-Lorraine, France. It's amazing how knowing that one name has led to so many new discoveries. To give you an idea, here's a screenshot of my family tree at Tribalpages.com, showing what I knew about Margaret before her maiden name was confirmed.
Here's a screenshot of it now, with all the info I've found so far.
This is why I love genealogy. No brick wall is permanent, and amazing discoveries could be waiting for you just behind the next document you find.
