Well, actually Negro Hill is what those that want to change it want to change it to.
I don't know what word they used back in the Gold Rush days to name that hill. If it was Negro as that was the spanish word for black, then I see nothing wrong with the naming it Negro again. My point is, the markers are not historically linked to the graves, so I see no reason to preserve them. Maybe I'm wrong, if the markers were the original markers from the graves and said "unknown N-word" died such and such year, then I would say that because it is the original headstone, it should be preserved. But I'm pretty sure the real history is, most or all of the graves were not marked with headstones, and the headstones are 1954-1955 creations which means IMO, they are not historically correct markers anyway for the grave, I see no reason to keep them. A 55 year old marker over 150 year old bones has no historical value in preservation IMO. That's my point.
Ok, so I have a little history book published by the Folsom Historical Society, "Images of America, Folsom, Ca." I see reference (p. 61) that the name "Negro Bar" has been around at least since 1851 when Father Ingoldsby conducted church services there. On page 56, there is a picture of the Picker building, now under Folsom Lake, but previously located on Mormon Island. It says, "other towns that once thrived in this area were known by these colorful names: Jenny Lind Flat, Negro Hill, Condemned Bar, Elephant Flat, Rattlesnake Bar, Red Bank, Maple Ridge, Poker Bar and Salmon Falls."
It sounds like Negro Bar was not very big, per the Folsom History Museum, it was "little more than a cluster of tents and shacks." According to other sources (
