Hi Cathy
You don't give their ages or whereabouts in Norfolk they were married, so not sure if these are the right ones.
In 1861, S Lynn, there's a William b. 1810 N Runcton who is a journeyman carpenter with Sarah b. 1807 King's Lynn.
They have Frederick, b.1833, William, b. 1837, Mary Ann b. 1839, Sarah, b. 1846, and Elizabeth b. 1842, all in King's Lynn.

PS Frederick is also a journeyman carpenter, William is a bootmaker and Mary Ann is a dressmaker.
