I am sorry to be the bearer of bad news, but you won't find fathers' names in a marriage entry in a parish register in 1733. At that date, you will just get the names of the two parties and the date. After 1754 you will get names of witnesses, the parish of residence and status (bachelor, spinster, widow etc). Fathers' names, occupations, ages etc etc appear from 1 July 1837 (the start of civil registration)

If you want to see the original entry (which you absolutely should), you can hire the microfilm at your nearest LDS centre
