I posted this message in the McNatt forum as well.
As there is evidence of early McNatts in Delaware (Richard McNatt and wife Rebecca Anderson) their son John, and Rebecca Anderson's parents (James Anderson and Elizabeth Brown) in the Mispillion Twp, Kent Co. DE area (see following link):
They currently only list 2 McNAtts, neither one of which are Richard or Johh. They don't list Rebecca Anderson's family and certainly there are others that could be added to the official registry if you have knowledge of them.
Please let us know if you register any of our ancestors!
