I have just received a birth certificate for my g-grandmother indicating that my g-g-grandmother was Elizabeth GRAVENOR. From 1881/1891 census she was born around 1848 in Nantyglo, Monmouthshire.

She married James YEM(M) (probably in 1867) and they lived in

I don't know her parents yet (I will order the marriage certificate) but the only Elizabth I can find on earlier census is in 1851 as a visitor without her parents.
