Help needed to find gt grandparents marriage

[Bristol Boy]

Could some one please help me find my Gt Grandparents marriage details.
They are John Camm born1841 Yate Gloucestershire & Sarah Jones (from daughters birth cert) born 1843 Llanvihgel Monmouthshire. Their youngest child Mercy was born 1873 Garndifaith Monmouthshire.
I cannot find them as a couple in the 71 census.
I have found some J Cs & Sarahs but none that match the surname Jones.
Thankyou Bristol Boy

Could Sarah have been married before? This marriage is in the right area and at right time:

Marriages Mar 1872
CAMM John Pontypool 11a 173
Farrington Sarah Pontypool 11a 173
Saunders Sarah Pontypool 11a 173
Walden Seth Pontypool 11a 173

... with Mercy's birth 9 months later, same district:

Births Dec 1872
CAMM Mercy Pontypool 11a 145

Possibly her first marriage?:

Marriages Dec 1864
>>>> JONES Sarah Pontypool 11a 267
LEWIS Josiah Pontypool 11a 267
LEWIS Mary Pontypool 11a 267
>>>> Saunders James Pontypool 11a 267

Possibly Sarah in 1871. No husband with her, but unfortunately the "condition" column is left blank so cannot tell if she was widowed, married or single:

Name: Sarah Saunders
Age: 27
Relation: Servant
Where born: Llanvihangel, Monmouthshire, Wales

Town: Newport
County/Island: Monmouthshire

Frederick Barfoot 42
Ann Barfoot 36
Frederick H Barfoot 12
Sarah Saunders 27
Sarah A Saunders 5
RG10; Piece: 5343; Folio: 58; Page: 16


The younger Sarah Saunders is probably her daughter (by James?). Interestingly, she was born in Gamdiffaith, same place as Mercy was born. This is probably her birth:

Births Dec 1865
Saunders Sarah Ann Pontypool 11a 139
