Hi laurie,
Can't see any Wiks in Great Shelford.
There is a John Wikes in Dullingham in 1634
And then with the name Wickes you have
Agnes 1588 Grantchester
Anne 1592 Arrington
Annes 1555 Toft
These are the only A's and the closest for you would be the Annes
Unfortunatly Toft christenings do not appear to have a batch ref in the IGI for Cambridgeshire
