Hello: John Hawkins did marry Mary Dew. The following is the info you need taken from records at Oxford: Hawkins, John, of the Inner Temple, London, Esq. married Mary Dew of Oxford on 18 February, 1679/80 at St. Michael, St. Mary Magdalen or St. Giles, Oxford. I believe the church records were combined and that is the reason the records give three different churches. However, since a christening took place at St. Mary's in Oxford, I believe the church where the marriage took place to be St. Mary Magdalen.
