When my dad started doing WWII reenacting back in '95 he had to pick a German last name as his persona. So he took a Germanic version of our last name "Landree" derived from "Landry", Landry originating from the Alsace-Lorraine region of France (or Germany, if you swing that way in a nationalistic sense). So I also use it for reenacting and I chose it since I joined a Prussian unit for NW originally.
But I have other aliases. "Nil" from "Mr. Nil" because I couldn't think of a name. Then "Kyyneltya" being a mashup of three words I can't remember and people would just call me "Kyyn" or "Ky" for short. Also way back in the day went by "Deadtomb" after a frustrating 30 minutes of not being able to get a screen name for some game. Also "Mathias2992" because at the time I thought Mathias was the coolest name ever and then 2992 for April 29th, 1992 mah birfdae :DDD Also had "Seither25" for another game, Seither being a weird off shoot of the band, "Seether" and the 25 because it needed numbers in it. :c
Wow, surprised I remembered so many from super duper years ago.
