Alan,
I think that this is a real long shot as the records for the 17th Century are quite sparse. On a web site that I subscribe to I searched for marriages in the name of George White between the years 1620 to 1690 and it came up with 64 records. One in particular was as follows:-
George White married Hanna Norton on the 1st May 1667 at St. James Church, Clerkenwell, London.
None of the other records listed the bride's christian name as Hannah or Hanna.
