Hi both

Is this 1881 census any use to start with? (The details match the 1891 census RG12/416 115 10, when he's a baker)

From there, this could be him in 1861:
1861RG9/685 141 3
Romsey Infra, Hampshire
Corn MarketOliver Vivash, head, 33?, Plumber & Glazier, b. Hants Dean
Mary, wife, 36, b. Mattisfont
Harry Albert, son, scholar, b. Dean Edwin, George, son, scholar, b. do.
Harry Thomas, son, scholar, b. Romsey
Mary Ann, dau, 4, scholar, b. do.
Kate Elizth, dau, 1, b. do.
Sorry, I can't manage to read the boys' ages but there's a birth registration for Harry Albert Vivash in 1849, which matches the 1897 death registration (Albert Harry Vivash age 46, Mar 1897 Reigate 2a 114)
I can't immediately see Oliver or our Harry Albert in 1871 but some of Albert's siblings are in the workhouse, and a brother is with family. I suppose that the 1862 death for Mary Vivash is Harry Albert's mum.
