Why yes, yes I did--thanks for asking!
In the front west corner of the cemetery I found him, by just walking around and reading the oldest looking stones. The monument says:
"JNO. P. SAND
11 MINN. INF."
If you don't recall his story, check this post from February. Either he was proudest of his service in the war between the states or burial-and-a-tombstone was a veterans' benefit. He enlisted in 1864 and spent 10 months as a soldier when he was 16-17.
According to this page from the 1890 census... (evidently, military records were stored elsewhere and survived the fire that destroyed the 1890 Federal census)...JP had a hearing loss from his service in the war. The job of deputy sheriff would have been offered to a vet before someone who hadn't served, so that may be how JP got into law enforcement. Again, that's just a guess.
I'd really like to know if any of his kids had kids, and if they realize who he was...
