We figured something or someone was buried there, but members of the family who lived here at the time (1919) had no idea what it was, including the woman who was actually alive at the time.
My wife devised this elaborate theory that a victim of the flu pandemic (http://en.wikipedia.org/wiki/1918_flu_epidemic) was buried there, although the epidemic had pretty well run its course before then.
I thought maybe it had something to do with WWI, but the armistice was in November of 1918.
Last night, we gave a presentation about our house to the local historical society, and an old guy there suggested that it might have something to do with the American Legion, which he said held its first national convention in Minneapolis in June or July of 1919.
Today I looked up the American Legion on the internet, and the convention was actually in November of 1919. But it got me thinking more globally than just the family who lived here, so on a whim I Googled the date. It was the day the Germans signed the Versailles Treaty! The family who lived here was German, so it must have been very meaningful to them.
Finally, after three years, I can sleep.
