Just found a great synopsis of of the name Faville (Fauvell, Favell). A Judge Fred Faville of supreme court of Iowa had secured the services of a geneologist to find record, if any, of remote ancestors. (Laurie--do you have a copy of this? If not, I can send you one.) I won't go into what he found in this message--English history. But here is a bit on the John Favill family.
He wrote that the earliest trace we have of any of the Faville tribe in America is the record of marriate of Thomas Favill and his wife Mary. There is more to this, but it seems that John Favill of the Continental Army was their son, I'm not sure if he was born to Thomas Favill or Mary's second husband (Thomas had died). John married Nancy Lewis (a "Mowhawk Dutch" woman). John was mentioned as "being in command at Fishkill." He probably held a commission, as he was called "Captain" by his neighbors.
This young couple lived for a time in New Jersey, and after the Revolution settled in the woods in Herkimer Co, NY, near a stream called "Faville Falls." Had twelve children, etc... The seven sons all grew to be old men. I have a picture of them taken in a group, when the youngest was evidently past sixty.
I also have an account of the family by Frank Faville of Dodgeville, who was the grandson of John.
