Judi,
You might like to know that the last Pinchon recently passed away. She was my 1st Cousin and God-Mother. The family had been made aware of the family history when the Springfield History Society, Mass. contacted them informing them that they had located them as the descendants of William. The founder of Springfield. The family had never left Essex and she spent all her life living and working in the county.
My research indicates a direct line but there may be other surviving Pinchon's out there.
If you come across any please do let me know in research. Thanks
Marcus
