Also as they Married post 1837 the Marriage Cert will confirm his Fathers name and occp.

EDIT I really think you need the M/C.
One Family Tree has Richard as the Son of Richard/Agnes
This I believe to be wrong.
Your Richard has a Brother GEORGE c 1825, Bickley, living with him and Eliza in 1851.
The George, age 15, that appears on the 1841 Census with Richard/Agnes and a Son Richard, age 19, is still with his Parents in 1851 Census. 1851 he is born Stourton.
Both George and Richard were probably not with their Parents in 1841 as they were old enought to work away from home.
