"So, did you ever find JP Sand's grave?"

Why yes, yes I did--thanks for asking!

Calvary Cemetery in Little Falls is east of the river on the north end of town and seems to be a mix of pioneer families' members.  It seems to be a public cemetery with old graves as well as fairly new ones.  Maybe Little Falls had a north and south division too (like Pierz did) since Oak Hill Cemetery is also public but it's south of town.  I'm just guessing here tho.

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
CO. G
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...
