The monument to Darlington is still there, BTW, at least circa 1987, when I last lived in the area. I used to cut across the Indian Cemetery mentioned in the article on my way to hunt & fish in the woodlands just north of there when I was a kid. That headstone was rather hard to miss.
I hot linked it.
