Benjamin ROUND and Sarah Oakley

[Trees]

A correspondent has a Family Bible bought in error and is attempting to find the family it belongs to
he says it is that of
Benjamin Round who married a Sarah Oakley in 1848.
I have yet to ask where 
Now I can not find any marriage for people with these names in or near 1848 can any one help please?
On the 1851 census there is a Benjamin with wife Sarah eldest child b 1848  2033 fo 397 p24
but no marriage in Worcestershire is showing up on Free BMD or FindMyPast
I would love to help relocate the Bible to the family
