Hi Sharon,
Had a look for your Zebina Jones - no luck.
Did find the following - might be of interest.
1851: HO107, 2449, 527, 50
Garndifath, Trevethin, Pontypool, Monmouthshire
Zebina Jones, 1812 Ironstone Mine contractor and Victualler
Ann Jones, 1815 (wife)
RACHAEL JONES, NIECE, 1838
Susanah Davis, 1832, general servant
Mary Evans, 1830, general servant
Could be that Rachael is your Zebina's sister?
