Hi,
I don't know if I am a descendant of the original John Pressey or not, but there is quite a bit on the Pressey family generally under that surname in the "England" part of Cyndislist. There it says the original John was thought to have come from Landford (that is the correct spelling of the place) which is in Wiltshire, England. I am researching my family and most of the Presseys were from that part of England - Downton, Redlynch, Hamptworth and other villages all close together in that part of Wiltshire. Landford is just a few miles away so it is likely the families were related. If and when I come across any more information I will forward it to you. Good luck with your search.
Regards,
Joan
