Marriage of William Weston Dunn to Harriet Gray. 08 02 1837 at St. Hilda's Church, Market Place, South Shields.
This is the record of my ancestor's wedding, but it gives no other details in the online version available.
The Record Source is given as Northumberland and Durham Marriages and the data provider is Northumberland and Durham Family History Society.
I'm trying to trace back to the respective families of the pair. Wiliam on many censuses is recorded as coming from Hull yorkshire and harriet from Scarborough, Yorkshire. However this marriage record gives no details of their origins, nor the names of any relatives.

My question is simply this, -is this transcription likely to include all the information on the record, or might there be other details to be discovered were I to make the long journey necessary to consult the original?
Any other ideas of how I might break out of this apparent dead end would be most welcome
