England births & christenings (1538-1975), records the christening of a Sarah Roddam, 22 January 1831, Allendale, Northumberland. Father is recorded as George Roddam, mother Jane.
It is likely this Sarah, had a brother christened George, 31 May 1834, Allendale.
Of interest, on 12 November 1821, there were two marriages for a George Roddam in Allendale, Jane Hall & Jane Teale.
