Just ran across his name in the Norwich Rate Book. He paid rate to poor in the parish of St. Peters Permontergate, and I would try there for baptism and parients There was only two other Gedney in this rate book, one John Gedney of St. Ellens, who was "poore" and I assume maybe the John Gendmey who came with John Pearse to America in 1637, as did the other John Gedney. Then there was a "widow Gedney", poore of St. Giles Parish in Norwich. This Rate book was 1633-1634 only, the earlier two volumes apparently lost. Hope that helps, trying to find the John Gedney who came with John Pearse as his servant.
