I believe I may know the answer to your question. Pulte Homes is building a new subdivision off of Shaw Rd. called Woodrush ... see website www.pultehome.com/woodrush
They only have two homes that are built so far. Yesterday we talked to the onsite agent from Pulte and we asked her why did they fence off an area at the entrance off of Shaw road and she said it was an old cemetery that belonged to the Murdoch family. It was up on a hill and there were no indication of a cemetery. I don't know if she had the family name correct. Who knows ... maybe it is the cemetery that you are looking for. The subdivision is easy to find. Just go to Pulte's website and it'll have directions. Good luck.
