Marriage in Tiverton or Bickleigh?

[aggiebagwash]

I am looking for the marriage circa 1840 in Devon for Ann Fewins/Fewings and Nathaniel Davey. In 1838/39 Ann had a son Nathaniel (Dart) Fewings in Creacombe, she is described as a widow.    Nathaniel came from Tiverton or Bickleigh depending on which census you look on. I have searched the PRO but can't find a reference to their marriage. Has anyone access to the Parish Registers for Tiverton or Bickleigh who would be willing to have a look for me for the period 1838-1841?

Thanks Mags
