I think the newspapers were Newcastle Courant & Durham County Advertiser of 30 June 1848.
A possibility for Mrs Jackson is the former Catherine Dobie of Tanfield, daughter of Sarah Dobie.
1841 census at Tanfield
Sarah Dobie 85 Inn Keeper
Eleanor Ayres 40
John Jackson 30 Surgeon
Cath Jackson 35
Newcastle Courant 17 Feb 1837
MARRIED the 16th Ult at Tanfield, Mr John Brice Jackson, surgeon of Tantobie, to Catherine, daughter of Sarah Dobie of Tanfield.
ADDED: I think John Brice Jackson may otherwise be John Bird Jackson, who died in 1845.
