Hi Sylvia: Many thanks for your response but the entry you have shown is not 'mine' as I know via marriage cert that Robert married Elizabeth M. Gelling in 1847. That part fits.

I have tried to find them via the children, even my grandmother, Eliza Catherine Kelly DOB 1863 in the 1871 census but nothing! They just seem to have disappeared. I know that Elizabeth M. died in 1882, I don't know when Robert died, but I cannot find Elizabeth in the 1881c! Thanks you again.
