Hello Roger,
I had a look through all of Stalham 1841 (not very long, only 16 pages) and there are no Bubbings.
Nearest I could get was a William Bobbins, age 49, Ag Lab, living with Elizabeth Bobbins, age 47, at Low Street, North Elmham.
I had a look at the Norfolk Marriages 1801-1837 CD, and there is only one William Bubbins marriage (mind you, it IS at Stalham).
"William Bubbins married Maria Flowerday, 25 3 1811, Stalham"
There's another marriage which is quite interesting too - at Stalham, Edward Bubbins married Mary Flowerday 13 6 1808.
Two brothers marrying two sisters?
