@Megan Thanks for looking. The marriage in Kent was between John Bishop, the Rector of Chillendon and Jane Ewell of Barfrestone. This is the abstract of the marriage licence (Canterbury Marriage Licences Vol II 1619-1660, images on FindMyPast)
Bishop, John, clerk, M.A., rector of Chillenden, ba., about 38, and Jane Ewell of Barfrestone, maiden, about 22, d. of Mr. Robert Ewell, clerk, rector there, who consents. At Barfreston. Dec. 22, 1627.
So at least we can rule out this John Bishop from the equation. And if he was the Rector in Chillendon, he wouldn't be having children up in Norfolk.
