Looking for John Wesley Marshall Mary Carse

I would be very grateful for further information on John Wesley Marshall & his wife Mary, allegedly my Great Great Grandparents.

So far I have his birth (bap) as 19 February 1809 in MORPETH, NORTHUMBERLAND, UK. I think they married c. 1833.

MARY CARSE was bap.17 Nov 1805 at Warkworth, also in Northumberland. I believe her parents were Robert Carse (Cars) from Alnwick, NBL and Elizabeth Dobson of Long Horsley, NBL.

Hoping someone out there will be able to throw some light on my problem.

Thank you
