Looks like your family tree survived WWI pretty well. Apparently my great-great grandfather died at the age of 29 at Neuville-St-Vaast in France during WWI. He is from my matrilineal "Taubner" line. Patrilineally, I am a "Hüttner." However, that's not my surname because of a complicated family history after WWII. I currently carry a surname to which I have zero biological relationship.
