I live in New Jersey. Thanks for the info on Hugh Mercer. I only knew part of his story.
Try and visit the Battlefield at Princeton. There you can visit the Ford farmhouse and stand in the room that Gen. Mercer died in. When I went there, the caretaker noticed that I was looking at the floor. He said to me "Don't bother looking; they sanded the floors in the '70s when they redid the house."
For years Hugh Mercer's blood stained the plank floors until they foolishly sanded it away.
