I have traced my ancestry from my grandfather, Frank A Hayden of Windsor County, Vermont to a great grandfather, William Hayden (1602-1669, who emigrated from Cadhay Manor, Devon, England in 1630 and landed in Dorchester, Massachusetts after sailing on the John and Mary. I have traced him back to Sir William de Cardon Heydon, (B 1045) who was born in Normandy, France as the son of Richard de Reviers Vernon.
The relationship between Sir William and Vernon is unclear and any information regarding them or other ancestors would be appreciated.
