Sharon and Derek – you asked about stonehenge like structures folks know about. Here is a link to google maps for an area in Centerville Delaware settled and greatly populated by the Dupont family, one of the 13 bloodlines. Open this page and follow Way/Graves road to the right from the wide Y intersection about 1200 feet up Graves road. Then look to the right in the field behind the trees. You will see an S curved wall structure and right below this five lintled standing stones with a black stone alter in the center of them.
If interested, you can also google map the Dupont Nemours mansion. On the bottom of the property directly across from the house and the pools (which are decorated with sea dragons, surprise!) is a temple to the false goddess Diana. It stands at the end of a grove. Imagine that!
Happy hunting.
