I had access to
Greetham Bishops Transcripts (LDS film, 1999578).
I don't know if you found your marriage, but I couldn't. There is a gap in marriages in the register from 1847 to 1857.
There is a George
Spriggs marriage, Dec 20 1842. George
Spriggs 23 marries Ann Noon 19. Fathers John
Spriggs & Matthew Noon. There is one child listed to George and Ann, Emily, bap.20 mar 1844. From 1848 to 1855 there are 5 children born to George & Mary Ann. (Sarah Ann, 1848, George 1850, John 1852, Elizabeth 1853, Mary 1855).
Am guessing you had all this already, sorry I couldn't help with the marriage you were looking for.
Would be interested in any connection you have with the
Garfoot or Christian families in
Greetham
