I know nothing more about his mother and father. However, I have found a record from 1841 census with a James Simmons, aged 17, Mother Sarah aged 57 - this could be them but there is no father. It says she was not born in England.
I don't think this one's yours,this James can be found in B'ham in 1861 & unmarried.
The info. I gave was for the family you found in 1841.
You need James' marriage cert.
This may be him in 1841:Late Lee,Great Barr:
Charles Ashford/35/Farmer
Joseph Ashford/13
Charles Ashford.8
Manoah Ashford/4
Ann Forster/55
Esther Clarke/25
Thomas Hill/50
James Simmons/12/Male servant/born in County
