It has been years since I looked at the looked at the Eytons of Shropshire, and I am writing this from memory at work, but as I know it…
Very little is actually known about this George Eyton and there are reasons to question his very existence.He is known from the Visitations of Shropshire p. 181 http://tinyurl.com/82rpjrehttp://tinyurl.com/82rpjre where he is given as a son Humphrey and a father of Nicholas.The Visitations can be very unreliable and this Visitation occurred almost 250 years after his birth.
His marriage to Jane Brereton comes from Burke’s Landed Gentry (another unreliable source) but is completely without support.There is no known contemporary record with a George Eyton married to a Joan, no record of dowry, no occurrence in an IPM, no transfer of property, no mention or connection of the Breretons to the Eytons in the Close Rolls/Fine Rolls/Patent Rolls etc.The only support comes from the church stained glass windows at Eyton where the arms of Eyton are impaled with those of Brereton (and these windows were installed much more recently than the taking of the Visitations).
The birth date of 1379 is not correct.It was certainly someone’s guess which has spread on the web but has no basis in fact.
The death date of 1476 is not correct.Nicholas Eyton was lord of Eyton decades before this time indicating his father was long dead.
There is no evidence that Jane Brereton existed and certainly nothing to say she was born in 1392.
I mentioned that there is reason to question George Eyton’s place in the pedigree.This is because the 1454 will of Fulk Eyton names Nicholas as his brother, and also names his parents as Thomas and Katherine.http://tinyurl.com/4af7d3xhttp://tinyurl.com/4af7d3x
Finally, I presume you asked this question here because descend from one of the immigrant Eatons to America said to descend from the Eytons of Shropshire.Unfortunately, this line has been broken as William Eaton of Dover was not the son Henry Eyton of Eyton, Shropshire.
