I'm trying to find George and Mary Oldham nee Vale on the 1861 census.
They might be in Wales as they had a child Amelia in Pontypool in 1857 and a son George in Merthyr Tydfil in 1860.
1851 they were in Leamington Priors, Warwickshire

1871 in Burton on Trent, Staffordshire

Marriage was 27 June 1848 in Ashby de la Zouch, Leicestershire
They certainly moved around a lot.
Mary died 1879 in Burton and George in 1895 in Burton
George was born in Newbold on Avon (Rugby) and Mary in Austrey both in Warwickshire
