Thats really nice of you to do that - kind of adopted the rock did you? It is great to keep local history alive like that.

I also do something similar. I live in a little town called Caln, about two hours west of Philadelphia. The area was settled by a family from Caln England in the early 1700's. The road I live off off is called "The Kings Road", now Kings Highway / Route 340.

It was a "Royal" road that ran from the farms in the area, all the way to Philadelphia, and was used for the rapid transport of the Kings Troops from the city to the surrounding countryside where the Lenapi and Delaware Indian Tribes were attacking the locals.

There is a small cemetery off in the woods near my property that has the remains of a small family and a few Royal Troops that were massacred in a raid. The local historical society knew about it and had some great information, but no resources to take care of it.

So, long story short, I kind of adopted it and keep it somewhat as best that I am able. On Memorial Day I put a Union Jack and a US Flag in the cemetery as some small way of saying 'you are not forgotten'.
